I have a gen 4 5.3 thats pretty much stock. The only thing i changed on it were the injectors, and intake. I installed an ls2 intake manifold, and 60lb bosch ev14 injectors, as well as a 2bar map sensor, and a hx35 turbo. Im looking for a base tune to get it atleast idling, so i can tune from there. Any suggestions would be of great help.
