A friend of mine works at a dyno shop, and told me that they got a near consistent 16-18 hp from just adding udp's and accel coil packs. Does this sound right to you? I didn't think coil packs would make that much of a difference.
Its the set-up i went with, you can feel the difference, but i didn't know it was that much.
That sounds about right... Generally, 8 to 10 RWHP on the UDP's, and betwen 6 to 9 from COP's, from what I have seen. I am pulling the trigger on the COP's myself here in a day or two. Either going with Summit Racing's, or Accel's.

GTbob;
could you check back in later and let us know what you go with, install, pics, results, etc.?
Inquiring minds want to know......
Will do! I ordered them yesterday as a matter of fact. I went with Summit Racing's brand. $269.99 for the set. I will do a writeup and install pics as I do them. Might be a little bit before I get to putting them on however. I just got promoted at work so the schedule change will take some figuring out.
