I had to adjust something around 15% on my car from front to rear.
After I said this I wasn't sure the stock OS allowed this. I have Big Stuff on my racecar and it does. However I just looked and HP Tuners does allow a Static retard vs Cylinder and an Injector Gain vs cylinder. I have never used this with HP tuners and there is a warning that some operating systems can cause high rpm operational problems when using this.

Stan, any plans to build a crazy fast 5th gen?
