I have 2007 WRX with 19K miles. Mods so far are:
Cobb DP (catted) and SPT 3" Catback
Run of the mill Stage 2 with protune - currently 238WHP and 260wtq on 93 octain
Looking for best bang for the buck to be about 350WHP or more. Or rather, I'd like to be low 13's 1/4 mile or high 12's would be nice. Before the tune I ran 14.0's all day, I know I gained a couple of tenths from the tune but haven't been back to the track.
All tuning to be done at P&L Motorsports in Chicago. They have a Dynojet Dyno. Plan to do the tune next spring or summer, depending on when I would get all the parts installed. They don't tune with opensource so I'll keep the AP unless someone has a better idea.
What do I need for Turbo and supporting mods? Assume FMIC will be installed, or APS TMIC. I'd also like to consider a tune with e85 along with the 93.
