Notes:

I am very impressed with the 2008 STi. Once I did the first pull on the car I knew it had potential. With some conservative tuning and only a couple pounds of boost we were able to punch out a 55whp increase and a jump of 45wtq. The fun started with the tuning of the new AVS Exhaust cam. The combination of AVCS INTAKE CAM tuning and AVCS EXHAUST CAM tuning gave us the ability to run very little timing and a AFR of 10.5 and still pull of such a nice gain. I could squeeze another 20whp but for a reliable, safe, fun STAGE 1. I feel that was a good enough gain. The car is very responsive and with the extended gearing makes the car an animal. More testing to come.

Thanks everyone. Yes, we are going to develop a new product line and stages for the 2008 Subaru STi. So be on the look out for more stages! I dont plan on changing the motor or turbo any time soon.

what do 04-07 read stock on that dyno

05'WRB · 02-14-2008, 07:16 PM

201whp on a stock engine? That seems to be a little low vs one dynoed on a mustang dyno.

Glenn,

Always doing big things. You've been down here, you know what goes on!

We have the dyno day this sunday and we have an in-house 1500whp supra that traps over 175mph that we have been working on. Probably put it back on the dyno today and see if I can squeeze some more.

I will be also playing with my 2008 a little this week so expect some new updates!

Awesome! We start at 9:00am! That Armada might be to much for my dyno to handle

Yes, with the AMR BIG MAF we picked up 10whp / 10wtq. The only tuning involved was the scaling of the maf sensor. Timing, AFR's and BOOST level were left untouched. We will be working on the new AMR downpipe's this week. Installation and Retune will happen the same day. I will start a new thread with the new HP data.
