What exhaust mods do you have? 7at?

Full list:
Aam intakes
Z1 upper and lower manifolds
Synolimit ported TBs
Momentum headers
Motordyne ART pipes
Invidia Gemini catback
UpRev tune

That's on a 6 MT

So you made +25 whp peak after switching intakes, upper and lower mani with a tune?

No no... much more disappointing than that. lol it was only 6whp peak, about 10whp at/near redline. All the intakes changed was a bit of a loss in midrange as per my tuner. With the exhaust mods + M370 + injen CAI it was 331/269.

My N/a result
 

Long tubes, cbe, intakes.

316 peak. Added more.timing and fuel was making more power. Uprev

I just got the aam intakes too, haven't installed yet. Did you remove the maf tuning piece from the intakes?

Yep I did remove them

I hit 317 with stillen gen 3 intake, fast intentions cat back, and fast intentions non resonated test pipes. I'll report back once I have the z1 ported upper and lower intake plenum installed and the car tuned with ecutek.

Your powerband looks crazy. Why the jump and loss in the mid range? Made great numbers, from the looks of it the 1st and 2nd didn't really differ besides in the top end, that hp isn't really as usable.

that the effect of losing power due to knocking....

Thats no bueno

Z1 intakes
Art Pipes
AAM Short Tails
DynoJet
HP: 326 TQ: 258

This with a tune?
Do you have the stock Y pipe exhaust or a CBE?
And is this in SAE, STD, or uncorrected?

I have the same setup, but RTP's, and the AAM midpipes. I'm sitting at 315/258 untuned. But I started at 314whp with just short tails... I'm just trying to find answers lol.

I can tell you that the 295 baseline is with my mods and no tune. The 326 number is after osiris tune.

I have stock y pipe and no cbe, just short tails, art pipes and z1 intakes

As for the STD, SAE i will have to check on that for you when i get home, i will get back to you.
