Steeda Intake and SCR Tuner?
I just ordered a Steeda intake and SCT tuner for my 2009 GT. Question is - will I really notice the horsepower increase by moving to 93 octane tune with the CAI? Will I notice the difference at lower octane ratings as well?
I'm also contemplating a 3.73 gear for the rear end, vs. the stock 3.30 my car came with. How much can I expect this to drop my MPG? I'm getting 18 mpg on average in mixed driving now, but only have 500 miles on the odometer.
