Get it to the track and lets see some trap speeds. That is alot better than dyno numbers because they vary so much from dyno to dyno,.....

Right on the money! I hit 309whp / 298 ft/lbs in my 04 with a VF39 on 91 octane and torco. If only we could get 93 out here... Only mod I don't have that you do is the intake, otherwise everything else is the same.

I haven't gotten to the track with it yet, because every time I switch to the torco map my clutch slips. I can't believe it has lasted this long... 90k miles!

The EJ205 / vf39 is a perfect combo... as long as you don't put 21psi through it every day it will last a long, long time.

Wow 21 psi is a lot for a vf-39 on a 2.0! Good numbers though.

Transmissions don't brake from bigger turbos, they brake from improper shifting/clutch operation.

Agreed. But this car should do well at the track. My car made 303whp/ 278wtq on Precision's dyno over a year ago. I trapped 107 at E Town last week.

Seems to be right on. I put down 300 on a dynojet 3 years back and trapped 106.5.

Glad to see someone else had another positive experience at Precision Tuning. I was there over a year ago and Cleo did a tune on my 04 WRX on an 18G Turbo Setup for me. Did 311whp/ 298 pounds of torque at about 22 pounds of boost. I could of done better but a blown clutch on the last pull wouldn't of helped They really know what their doing at Precision Tuning.
