I have two manual cars that are on similar bolt ons and no throttle problems or boost issues at all. Mine in the log when says predicted torque source it has trans up so using trans limits to set the throttle. The car on 72 percent throttle and 12 lbs ****ing flys but watching the log I know its not all it could be so now going to just send it off. I will say I was smart enough when I had the nose off doing my heat exchangers to move the tcm from off the front frame to up next to ecm. Now its easily accessed as I knew at some point it was going to go off to get done. Just didnt think I was going to be up on it already on these mods.
I can't wait to hear just how well you car responds from the TCM tune. If you can beat your previous best now that the summer's here, it's gonna fly when the good air comes back.
