Modded 06 WRX Protuned w/chart.

Well the day finally came!

I drove my car the 150 or so miles to get to Harman Motive in Torrance CA today and finally got my 2006 WRX Protuned.

Mods:
K&N Panel Filter
STi TMIC
Invidia V3 Catless Divorced Wastegate DP
Cobb SS3" CBE
Cobb AP V.2

With those mods I managed to squeaze 227 WHP and 272 WTQ at 16.3 lbs of boost. This ended up being enough to be the strongest '06 WRX that they had ever tuned.

The baseline was with the Cobb Stage2 map installed directly through the AP V2. So you can see that the stock map from cobb is actually quite nice when it comes to smoothness. I must say though, after tune, my Christine pulls like a real bitch. I actually felt that I had to restrain myself when wanting to get on it from a light, simply because it feels so friggin fast now.

As far as gains go... gains were great. I am very happy with the results. For those wondering what the next step would be... Bigger Turbo. And that is a step that I am not going to do to this car. That is for another project. So... except for a GP Moto silence delete mod, this is it for power modifications.

All in all... its been a long time in the making, but I was grinning all the way home.
35 runs and every run was as solid as the previous run. The tuner was visibly impressed. HUGE to the guys at Harman Motive, Harman Motive!!

See attachment for the proof.

That's a conservative tune. Is that what you wanted ? Might wanna ask them to tune it a "little" bit more aggresive, up the boost to 16.5 or so. AF is a little low as well.

boost doesn't make power, airflow makes power. There comes a point where raising boost actually reduces air going into your engine and thus reduces power. People obsess so much about boost numbers as to think that 16.3 is inherently worse than 16.5? Sheesh.

The boost numbers on the dyno read about 1psi lower then the bost numbers on the engine itself. He was just using the dyno boost numbers as a guide. My manifold boost pressure is 16.3 as max.

I dunno about the A/F Ratio graph. Its consistant with the amount of timing advance he ran. I dont know THAT much about A/F Ratios to be quite honest. Just know that the car never feels fuelstarved or too rich right now. If someone can explain to me why my A/F graph is bad I will most definately as the tuner!



*Edit
Oh.. and the dip in both HP and TQ at around 4000 is a Cobb problem. My tuner tried around 20 pulls or so to even that out, and what happened was that the Cobb AP did not manage to override the stock ECU at that point for some reason. He said that Cobb had told him they fixed the problem, but obviously did not. Evidently not THAT many 06 and 07's have gone on the dyno, mainly earlier models. He said that once Cobb find a way to completely override the stock ECU he would send me an updated map that would clear that right up.

having a 2.0, I am quite envious of that much torque before 3800rpm

Congrats!
