Dearest Evo friends, I have a 2011 lightly modded GSR that desperately needs a new tune. (modifications listed below) Can you please recommend anyone other than AMS and Strictly Modified? What are your thoughts on Boostin Performance? I live in the Chicagoland area, and I would be open to a road tune or dyno tune. Any help is greatly appreciated.

ETS Intake, Cobb XLE BPV, Grimmspeed 3port, MAP UICP, Walbro 255lph pump, MAP o2 eliminator downpipe, MAP testpipe, Buschur crossflow exhaust

Thank you!

 

Easy.

Boostin Performance. They are a major ETS partner and Devin has many track proven cars. I've been going there for two years for everything from turbo upgrades to oil changes. There is a guy on the forum with a built motor from them that he beats to death and has 50k miles on it if I recall. I think it is in the Midwest forums.

I've used AMS in the past and the reputation is warranted, but they've moved on to more expensive platforms.

If you want to talk more PM me your number.

 

And the irony in both of our account names...

 

This Evo sounds really slow...................

 

From what I've heard, Boostin is the boss.
