and you guessed it, problems again. My heater was acting up and it turned out that my transdeucer was leaking N2O, so I threw it away and plugged the hole. Then I was having the same issue as before where the a/f would rise up, level of and the rise again. I guess you could say stair stepping. If it would just go lean and level off that would be an easy fix but not this. We pulled the fuel line out the nozzle and test fired it and it seems to be flowing steady. I was expecting it to pulsate but it didn't. We checked the voltage to the fuel noid and it was like 11.3, but the battery had like 13.8. We came to the conclusion that I need to rewire the system because I've removed the noids so many times and I have many, many butt connectors. I need to solder the wires together this time. I got home and pulled apart the relay and the posts looked funky, so I cleaned them up and check the relay and it's working fine. At this point I'm now at 12.24v to the noid. This weekend I plan on doing the rewire job. I may move my noids around so anyone with the nozzle setup please post pics of where you have your noids mounted.
Sorry to dissapoint ya'll but I will get this sh!t straight and get some track time in.... soon.
On a plus side I went 203.5 miles in 8.9 gallons giving me 22.86mpg, which included some nitrous testing.

You just can't get a break when it comes to tuning huh.

That sucks. I'm the same way, as soon as I get something working something else seems to break.

even though the issue isn't there fault, they didn't charge me anything. It was my 3rd time there and I've had gremilins everytime.

Damn man. Sorry to hear about that. I can't imagine how frustrating that must be. Keep your head up. You'll get it figured out, and it'll be worth every second!

Don't worry, bud. Once you get everything worked out you'll forget all about it the second you see the numbers and the first time you lift the wheels up off the ground on the track. [sm=gears.gif]

Tough break man... I'm heading back to the Dyno on Saturday because of similar tuning issues. Mine lurches and diesels at part throttle medium load, and what a PITA that is...

Ouch, good thing your shop is being good with you and didn't whack you any for having problems on the dyno.

I would have probably left and set the car on fire if it acted up while being tuned and essentially wasted my money.
