My friend wants to get a professional tune from someone that really knows what they're doing with dsmlink. He lives in Carthage, IL but is willing to drive within about 3 hours.

His car: '95 GSX, built 6bolt 2.0 block and ported head, 280 cams, borg warner s258, 3'' exhaust, FIC 1600's, aeromotive afpr, dsmlink v3, gm maf, currently street tuned on e-85 conservatively by the previous owner. supposedly makes around 500-550whp, ran 11.5 @ 129 at the end of the 2012 season

Are there any good shops down in St. Louis?

Some other places he'd be willing to drive: peoria, bloomington, springfield, iowa city/cedar rapids,davenport/rock island, east moline

He doesn't want to go all the way up to Chicago, even though i keep trying to convince him to take it to Boostin Performance.

If he's willing to drive roughly an hour and a half more than what he originally wants to then I'd say go to boostin performance in hoffman estates IL!

the best place to get your dsm tuned is a guy named rat in Chicago il i will try to find his contact info .

there is a guy in ballwin mo named jason stange. he is on gatewaydsm as jrstange. He is my tuner and the only guy i let tune my car. guy is a computer software tuning nerd. Its all street tuning but will not blow up your car. he is very safe and explains everything to full detail to help you understand. I trust him 100% with anything with my car. his is a stock motor with a 20g that pulls on r6s get on gdsm gatewaydsm.org the local guys can help you. i wouldnt take my car to adrenaline, or pur performance. if any shop maybe matt at htp in high ridge but idk if he even tunes. just my 0.2

Boostin performance!! Can't say enough good things about devin. Had my old evo8 tunedby him, and this summer he will be tuning the GSX.
