OK, this is for those of you running a Steeda CAI and using the Diablo Preditor on your GT.
What tune are you using? Did you use a tune from Steeda? Or the Steeda CAI specific tune that is on the Diablo web site? Or your own custom tune? Anyone know the difference between the tune from Steeda and the tune from the Steeda CAI tune from the DiabloSport web site? If you use your own tune, what did you tweak from the Steeda or Diablo tune?
I got my Steeda CAI today. Installed, downloaded the Steeda CAI specific tune for my CALID from Diablo. Flashed the PCM. Good news is, no CEL. Now, as for drivability. When you stomp it, it runs like a spanked ape. No problems there. But normal driving, standard (light) acceleration, it feels like I am pulling a friggin trailer. At least up to 3k RPM. After that it seems to pick back up. But anything below that is kinda annoying. Pulling out of the garage and down my residential street to get to a main road, I actually had to look down and make sure that I didn't leave the parking brake on.
So I know that there are people out there that have not made it to a dyno yet. And yes...I know..get it on a dyno. Back to my point. There has to be people out there driving around with the CAI and a tune ( no dyno ). How does yours run? Notice anything similiar to what I am trying to describe? Did you adjust it out by adjusting your tune? If so, what did you adjust?

i used the steeda cai tune that came with the diablo from steeda but it also had the charge motion plate tune with it, and i think i kind of noticed some thing similar to what you are talking about but i guess i just really didn't want to ADMIT IT. i am having a dyno done in 2 weeks so i am hoping i can do a custom tune over the steeda tune with all the after market parts i have on my stang i am sure that some tweeking can be done to free up some lost power on a non spacific tune (that being the steeda tune)as well asthere are so manny more efficient parts working togeather.

I was having the same problem with mine when I used the Steeda CAI tune that came with my Diablo from also purchased from Steeda.
I am currently using the Performance Tune that came in the Diablo and I am running the timing +4 and had to richen the mixture 1% otherwise check engine came on saying TOOOOO lean. I installed the Steed CAI at the same time. Using the Performance tune with these changes she runs great. Sounds mean too!
I did send an email to Gus at Steeda who has helped me in the past and he has yet to respond. That was last Thurday.
Talked to Steeda today about this issue. They say that no one other than me has reported it. The suggested "fix" from them was to always make sure I have the traction control turned off. Hummm..... not exactly sure how this is going to help, but I will try it for a day.

/WAVES THE BS FLAG. i can't see this fixing the prob either they get the tune right or you custom tune i don't see any other fix besides taking the cia off and the charge motion plates as well and just running stock (not an option for me). i also checked it out today when i was driving seems like it is off an on some times my stang takes off like a prom dress at prom night. (no hesitation if any one has not experienced that)and won't slow down till i let off the gas. and other times around 1500 to 2900 it seems like it is not as responsive as it once was with light working of the throttle. but if i romp on it all the way threw the power band it is responsive. maby i am imaging this but i am hoping with a custom tune it is more consistenly working for me instead of against me.

Well maybe if enough people start to complain about the same thing they will adjust their tune, or at least check in on it. I did notice tonight that my air cleaner had partially slipped off of the retaining ring. I put it back on, tightened it some more, and it popped right back off. Just another tidbit in the saga

Got this reply from Steeda on that one already:
Sometimes there is oil residue on the inside diameter of the filter were it attaches to the velocity stack. Make sure you take something that will remove grease and clean this surface. Make sure to also clean the OD of the velocity stack. Also make sure the clamp is as close to the shield end of the filter as possible. This should help.
I did this to mine yesterday and it seems to be staying put 24 hours later.
As a result of the poor performance (referring to the Steeda CAI tune) I have loaded the Performance Tune with the timing advanced 3 degrees (4 resulted in a little pinging) and the WOT running 1% rich in both ranges (got check engine light for too lean without this). I have also lowered all the fan settings by 30 degrees. With these settings power seems great and no apparent weaknesses through the gears.
I did not necessarily ask for a reply though. Kinda of my fault.
I will send another message asking if they have any ideas.
I have not had the time today, but tomorrow night I am going to try your suggestions to a custom tune and see what difference it makes. This is my first real dealings with Steeda. Do not want to jump the gun, but their customer service after the sale seems to be a bit lackluster compaired to their service prior to the sale.

Just an FYI, the custom tune that I have created works fine with the 87 octane I am using here in California. If you are running higher octane you can try going a full +4 on the timing. If you do get some pinging just pull it back a little.
my steeda would not stay on every time i opened the hood it was always either off or partially off. didn't matter how tight i put the clamp on there it would just come off. so using my air craft crew chief skills i put a plastic adhesive around the ring and the lip of the air cleaner. that B*%$# isn't coming off now.

I broke out a can of carb cleaner and a couple of paper towels and wiped down the inside ring of the air cleaner and the ring it mounts to. Stayed on all day so far...... Of course that could change at any time.
Finally got in touch with someone at Steeda today besides the guy that answers the phone after everyone else has left ... ok, well actually it sounded like the same guy. But anyway. I explained the way the car was running. He said basically just go in and adjust the tune by 10% ( which according to him will make a 2 degree timing advance ). Retune it, drive it, if that doesn't fix it, do it again. And just keep going until I feel it is performing better. Not the most professional advice I have heard, but it was better than what the guy there said yesterday. I asked if I should do it for the entire RPM range or just up to about 3500. He said "Oh either way, shouldn't hurt the top end. And if it does then just turn it back ".... I'm thinking I need his job.

Since we are having what appears to be the same issues (NO power below the 4,000 RPM mark) I would try pulling the timing back for that range only. I do recall that when I was using their tune, performance improved the higher the RPM's climbed.
The CAI Tune that Steeda sends with the Diablo advances the timing by 4 degrees from the stock tune. With the Diablo you cannot go beyond this as 4 is the max advance unless you use the range selectable percentages. Maybe that is why he told you to go 10% and not a number, hmmmm?
I would think that going beyond the 4 would not improve things but I am NOT an expert. I would expect that you may start to get some pinging actually. Are you running the 93 octane that this tune is designed for?
Give it a try with 10% advance and see what happens. If it runs better great. If not, try the 10% pull back. I would try it tonight too but I am kinda tied up. Soonest I can play with my tune is tomorrow at lunch.
Well, I just increased the spark 10% ( maxed out ) on the 2k to 4k range. Made a little difference, but not much. Might try your route and use the diablo performance tune and see how that works out.
And yup, running 93 octaine

Well, it's not just the three of us having this issue. Found someone over on the mustang source forum board complaining about the same issue.
Just curious, what are you guy's CALLID? Wonder if that might have something to do with it since no one else has chimed in on the issue.
mine is FBJR3G5
BTW, I tried the Diablo 91 octaine performance tune, adjusted the WTO by 1%, adjusted the 2k - 4k range by 4. It runs like a new car on the low end now. In my opinion it does not pull as hard as it used to on the top end. More like driving it stock.
