I have a 2017 L83 with a stock engine and a Magnuson supercharger. I am replacing the engine with a fresh build that includes LT4 injectors and pump and a stage 1 Positive Displacement blower cam.
The current tune file came with the supercharger through the team a magnuson . What would i need to alter to just get it to fire and run.
Ive heard it wont even start with these injectors.
The canned tunes from those companies are usually not super great.
BTW. You should read about adding a SCIAP sensor. It makes an absolute tremendous difference in driveablity with a magnacharger or any PD style blower.

I know the pump is super pricey, but you might want to look into that too. You can wind up starving the rails with too small of a pump with the bigger injectors.
