Default 04 WRX VF34 Dyno Tuned

Well I had my 04 WRX dyno tuned this last weekend. Overall it was a good experience. Pretty nerve racking watching her getting revved up so many times, she does have 88,000 miles on her! Tuned by Bobby at PRE in Portland. Very nice and professional people to deal with. Tune was done on a dyno dynamics dyno. I previously had a road tune done so i never knew my actual whp that i was putting down.

Mods:
IHI VF34
APS DR525 FMIC
Sti 565cc Pinks
Walbro 255lph FP
SPT Intake
Vishnu Uppipe
TurboXS Stealthback
Prodrive Axleback
NGK One Step Colder Plugs

Old Road Tune: 267 whp and 249 wtg on 92 oct at 18 psi
New Dyno Tune: 293 whp and 273 wtq on 92 oct at 17 psi

Chart of New Tune (sorry my work only has a black and white scanner):


I don't know really if this is indeed good? But it looks to be ok numbers for a VF34 from looking around

Yeah, that's damn good, especially on a dyno dynamics as they are on the lower-reading end of the spectrum.

I agree. I'll be taking to the track when they open back up in spring.

Why can't you say who tuned the car if they are not a vendor? Its braggin rights, not vendor tuned braggin rights, and its not like the tuner is the one posting ur car.

I really didn't know if I could or not. I changed it so if I can't I'm sure a mod will let me know.
