My basic setup is as follows:

2002 WRX Wagon
Built block/head (EJ25/B25)
FP Green HTZ
Killer B Holy Headers
Tial EWG
TurboXS Catless DP
Borla Hush Exhaust
Walbro 450 hardwired
PPG straight cut 1-4 dogbox
Carberry ROM running flexfuel/Speed Density

The issues:
First, initially during 93 octane tune session, the EWG wasn't opening at all (so boosting to 27psi at 400whp, no Bueno), no matter what John did on the tune. He proceeded to trouble shoot by removing a bunch of parts to get to the EWG. Thankfully, it was just a torn vacuum line, but was just a pain for him to get to.

Second, my car being a bugeye, the openport sometimes doesn't flash, so he busted out an older cable to make it work.

Third, the baseline tune needed A LOT of work, which I know is part of this service, but John had the deep experience and engineering background needed to tear and rebuild the map.

It got tuned to around 430whp on his Mustang dyno at 21psi on e85, with my IDC at 85%. Having tossed this car around a bit today, I wouldn't want anymore power, as this is my DD.
