Headers/ORY/Tune= 3 RWHP??? WTF??

Dyno jet said it pulled 301/ 312 on a stock motor with Jet-hot 1-3/4" headers with ORY, SLP cat back, and a tune! 312 tq? Thats less than stock?????

I went before without the headers installed and the car detonating on the dyno and pulled 298 RWHP!

Yeah the temp has gone up, bet we were inside and conditions were only a little better outside! SHouldnt I be around 315-320 RWHP??

This is bullshit!

Post the dyno sheet so we can analyze your tuned a/f ratio.

Dynoing in 112-116 degree weather kills performance. Who did your tune? Where did you dyno at? Xtreme?

This is an A4. I took it to a different dyno. But they were both dynojet. I had it done this time at Gearhead garage

A4 eats up power at the wheels.

Different dynojet's are not apples to apples comparison.

when I first dynoed my 2002 WS6 it just had a TSP lid and cutout and it dynoed 327rwhp 343rwtq and now after long tubes,3" X pipe, bullet mufflers and a Yank 4200 stall on a different dyno it baselined with those added parts UNTUNED at 288rwhp 290rwtq, and then after the TUNE it picked up 15rwhp and 23rwtq but it now shifts at WOT on the 2-3 and 3-4 shifts and drives much,much better but the big ol' stall eats up those #'s and different dyno's will read different so don't worry too much about dyno #'s but more about ET's thats where the win and losses are at!
