Currently I'm running the Cobb stage 1 with the green filter and a custom exhaust (magnaflow). I will be installing a cobb fmic on monday. Should I run stage 2 which cobb said was fine for my setup or should I do a custom tune? Personally I believe my car can handle much more than just the stage 2. I contacted a protuner shop that cobb recommended and they charge $500 for a dyno custom tune for my car. They suggested I get the downpipe from cobb, but I'm questioning if that is really necessary. What kind of hp/torque do you guys think the car can safely hit at this level of upgrades? And, are the tunes you are getting from I guess email from Randy and the other folks far superior to the ots maps. Thanks
