New Upgrades Coming!
Thanks for all the previous help. I recently removed my charcoal filters (thanks to this message board). I also just received my sprint booster and sent my ecu to renntech for upgrade.
Has anybody had their ecu upgraded at renntech? If so, what should I expect?
Although I received my speedbooster, I do not know what it does or how to install it. Can I get some help here also?

So you just buy upgrades to upgrade? Well I have am AMG sticker that ads 50hp to the wheels for $200.00 100% MONEY BACK.
Just kidding I did the same thing.
The booster you will love the feel of the response as for the ECU you make the call. I have both and would buy them again. Renntech knows thier sh%t!! I also have the headers and lowering module. The fact is get all you can get for upgrades, which by the way is not much, and have some fun with your car. I have done the AMG Challenge day and these cars are race ready. ESP off is great but learn the car first
then DYNO MODE
don't ask. Look up the post "Hello? sprint booster install" these cars can handle mor than you think.
