Default EQ - 2010 STI Cobb Stage 1 vs. Custom Tune

This is a 2010 STI that came in yesterday for a custom tune. The car was bone stock running the Cobb OTS Stage 1 91 Octane map, so we decided to do a couple baseline pulls before proceeding. This is the black line on the chart. The Cobb Map was putting down 215whp/247ft-lbs. This is a bit lower than expected, but everything seemed to be running safely.

After the baseline pulls, we installed an AEM CAI and GrimmSpeed 3-port EBCS and proceeded with the custom tune. The customer wanted the tune to be very safe and didn't care much about the peak numbers. After the tune, we ended up with 239whp/261ft-lbs keeping things very conservative. I could have easily gotten another 4-5whp out of it, but that's not what the customer was after, so we stopped there. You can see in the graph that at 4k RPM, we have a healthy 30ft-lbs gained and above 6k RPM, we have a about a 25whp gain. These are very healthy gains for a relatively low reading dyno and conservative tune. The car is also much smoother and more responsive all around.

Here's the info and chart:

Event: Custom Dyno Tune
Location: Equilibrium Tuning - Fairfield, CA
Dyno: Dynocom DC-Tuner AWD Chassis Dyno
Ambient Temp: 65 Degrees Fahrenheit
Elevation: ~100ft above sea level

*** Standard Dyno Chart Disclaimer ***

This dyno reads low and should be compared to the lower reading mustang and DynoDynamics dynos with no correction factors. Here are some proven numbers and trap speeds for reference:

Stock 02-05 WRX - 155whp
Stock 04-06 STI - 215whp

265-275whp - 107-108mph traps
300-310whp - 112-113mph traps
325-335whp - 115-116mph traps
350-360whp - 120-121mph traps

Thanks

Thanks. We always try to do a baseline when possible.

Thanks for posting. Nice tune. OTS Stage 1 numbers look a little low, but you made some good gains with the tune.

Just curious, what does a stock 09+ WRX read on your dyno?

I actually haven't had a stock 09+ WRX on this chassis dyno yet, but on my road dyno software I usually see about 210-215whp out of the 09+ WRX. This chassis dyno reads VERY close to my road dyno software, so I imagine the numbers would be similar. Interesting note, I usually see 08+ STI's put down about 200-205whp bone stock which is about 10-15whp down from the 04-07 STI's.

That is funny. Any thoughts as to why?

Also, these pulls were done in 3rd gear. I did tuning pulls in 4th which brought boost and torque in much sooner, but I figured it would only be fair to compare with the Cobb map in the same gear.

Not too sure why honestly. I imagine its in the stock tune as they usually end up making similar power after tuning.

FWIW, we had a bone stock 2011 WRX at our dyno day on Sunday and it put down 214whp.

Thanks
