Stage2 25hp upgrade??? 09 wrx sedan

**AtomicFrawg** · 03-08-2009 07:34 PM

I took my 09 wrx out to Corr Performance ( Great guys Btw!

) to test stage 2. Now this does not seem right. I only gained 25 hp from stock when flashed to Stage 2 93. They are getting the system to become protuners and will get them to tune it. But the claim on cobbs part of 19% hp was not reached. Im just wondering why I only gained 25 hp.

Mods.
invidia catless DP
AP CBE
TubroXS CAI
Green is my stock run pulled on Feb 2.
Blue stage 2 was pulled yesterday

Just staring at a dyno graph doesn't really tell much.Thats why when you see people that have been professionally tuned their graphs will include boost plots,AFR plots,elevation information and ambient temps.

I dynoed mainly for a base line with a stock Cobb Stage2 map. The low numbers just surpised us. This one has A/F added. They are protuning it Friday and I will post results here.

Thanks chris

I hope that is not a before and after AFR.Is the one at the top thats a straight line with the intake?

Was the first run without ANY modifications? and the 2nd run with ONLY Stage 2 modifications?

The A/F chart starts from the left (under Dynamics) and ends on the left (right of the s in dynamics). Its dives down to cutoff rpms then spikes up on the coast after the pull.
