I plan to do a tune on my E39 M5 soon and I live in southern Oregon... midway between Portland and San Francisco. I posted a thread looking for reputable dyno shops in NorCal. This thread is for shops in the Portland area. So far I've had recommendations on FB for the following:

Performance Speed Industries
6103 NW Casper Pl
Hillsboro, OR 97124
503.431.1395
Home - Portland Speed Industries


VIP Performance
8216 Northeast Sacramento Street
Portland, OR 97220
(503) 257-1110
Home - VIP Performance


Performance Race Engineering
13339 Ne Airport Way, Ste 500
Portland, OR 97230
(503) 619-0055
PreRacing Performance Car Parts, Forced Induction Systems, AWD dyno tuning

Has anyone had any experience with any of these shops? Anyone have any other shops they like that aren't one of these??

Thanks!!

Wouldn't you want to go back to PRE? Its going to give you the most accurate numbers to measure increased power.

I'll run my current stock map first for 3 pulls, then load the tune, then run 3 more pulls... so my previous numbers aren't necessary since I'll have a direct comparison on the same dyno on the same day... the ideal dyno scenario!

I would highly recommend Lab22 in Portland, OR. They cater more towards the E46 M3 high horsepower turbo community. The shop is all new state of the art & very high tech.
