Who did your tune? I have heard the same thing about the strupp headers and would like to know about the gains as well. Are you installing them yourself?

Dave@ FT did my tune as well and told me about the special they were going to run for the header/install...I think he told me $900 for the headers and install, not sure if that is a good deal or not..I don't know enough about those headers to know if it's worth it.

900 aint bad i guess... I got my headers online for 400... and he said rought 400 and change for install..Dave is a cool dude though. He told me those headers give really good gains midrange. I'll post my dyno tomorrow! Watchin the yankee game.. If they keep up.. tHey go to WS!! lol... And my scanner is not currently hooked up lol.. But yeah.. I'll post Dyno tomorrow. 240whp average or low prior to tune? 260whp sounds about right though after tune.

Well, 20whp is among the highest gains I have ever seen from just a tune. Also, I have only seen a few(myself being one of them) dyno over 250whp on his dyno in uncorrected form (NA of course ). Just take a pic of the graph and post it. Dave is def good people.

P.S. **** the Yankees .

I made 263whp on Daves dyno. My car about 10 more wtq than yours though. It helps a bit that you have a rev-up. In my opinion headers are a waste, but they are more beneficial on rev-ups because the cams have more lift and duration than non-revs. I made 282.5whp on a dynojet.
