AMS project 07 STI Small bolt ons, HUGE GAINS!

Thats true, but a good tune will really help fix a lot of that. Most of the difference after the tune is just perception and a change in throttle response. You can't negate ALL the extra piping but it really doesn't bother the overall setup considering the big time improvement in timing and consistency. I was able to improve throttle response some by going to a blow-thru maf.

If my STI doesnt sell I will seriously concider buying a FP green kit through you guys after you have done all the testing for me. I have played with a lot of turbo options, but didnt want to be dissapointed with what I got only to have more down time and out more money. I will let you do the work for me.
thanks

In the midst of our very chaotic move we were able to get my car on the dyno and finally test this bad little boy. The results were very nice and we are really impressed with the turbo. The car is now making 75 more WHP at Redline on pump gas!
On with the test
The Vehicle: 2007 Subaru Sti
Modifications:
AMS Custom Catback
Turbo XS Downpipe
AMS Test Pipe
AEM Cold Air Intake
Vibrant Header with up-pipe
Deatschwerks 850CC top feed injectors
Walrbo Fuel Pump
Forced Performance FPGreen with an 8cm turbine housing and 2.4" Inlet
Forced Performance High PSI internal wastegate actuator
STOCK TOP MOUNT INTERCOOLER
pump Gas
21 Psi tapering to 18psi
Mid to low 11's AFR's
The First graph here is just the numbers. Here is what she did last night on the dyno. we are pretty impressed!
Now here is that same graph in STD Correction for those that are used to using the "Standard" Correction factor
And last but not least here is the HP curve outlined over the tune with the stock tubro. All that was changed was the FPGreen and the fuel modifications to support it. Look at the HP increase at redline!!!
All in all we are very happy with the results and considering the spool time we will deffinetely be recomending this turbo to our subaru customers.
Next on the modification path is to try this same combination with our AMS Top Mount Intercooler, Remove the Tumbers, Try an FP 3" Cover and toss an External Wastegate actuator on it. Oh, and of course throw some real gas at it
We think with some better boost control and a little less heat soak we can squeeze close to 400whp out of this little bolt on turbo.
