Hey guys got a couple of questions about my Cobb Access Port V3. I currently have a 2010 GSR and have the following mods: Invidia DP ( no cat ) Invida N1 Catback and the DIY Intake mod. I was wondering what map you would suggest for 93 fuel. I will be getting the SF intake soon but my main concern is the DIY intake mod. I'm assuming a stage 2 map but not sure what one to use. Ive been driving this car stock for over a year now and im ready for some more power.

 

Get a real tune / etune. Don't waste you time and your motor's health with Cobb's OTS tunes.

 

I second this

 

Alright then e tune it is I don't know of any reputable tuners in St. Louis. Does anyone have a suggestion as far as a good e tuner? Thanks for the feedback too guys

 

Golden or Baka Unchi are prime E-Tuners.
