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.
I have already been reading some stuff on the elbow. I guess we will see. This one isnt the super low profile one but if we run into this problem im sure we can fix it. If not, COPO hood and Holley high ram time.
