Looking for shop in PNW for Whipple Supercharger install and tuning

Ernie at EPC is the guy who did mine, I couldn't possibly recommend him enough. He did fantastic work. I know he's further than you wanted to travel, but if you were looking for feedback on his work, I couldn't be happier. He had it for...2 and a half days start to finish, but I did buy a new ECU to do the replacement so my truck wouldn't be down while he was working on it. He was able to find the ECU for me, which was not an easy task at least at the time.

I also had him install performance dual springs on mine as I was right in the middle of the build range when GM had that defective spring issue that was killing 6.2s, and I had just put a blower on it so warranty should a spring break...right! He did phenomenal work on both jobs.

Thanks for the feedback! Did he do any custom tuning for you or was it using the canned tune ?

It was just the whipple tune. Im unclear on if the hp tuner credits necessary to download that tune could also be used for a custom tune. I would expect so, but not sure.

If i wanted a custom tune id definitly go to him no question. There are TRXs around making a smaller pulley really appealing haha.

He has a dyno, if youve seen my youtube videos of the borla exhaust, the dyno clips are at his shop. He does tuning. Last time i was there he had a Challenger Demon in getting its stock blower replaced with a 4.5L whipple. There was a turbo charged jeep srt there which apparently lays down about 1300hp. He also had a classic mustang on a lift which was getting a complete build up from the bare body. Hes got a Camaro as his personal vehicle and a truck i think.

Basically, dude knows his stuff and has lots of experience.
