Stock pistons and rods? I can’t watch the video, my internet is too slow.
Yep, bone stock 180,000 mile 4.0 never even opened up the motor. Basically bigger injectors, a piggy back ecu to add fuel with boost and thats it for tuning. Also had an a/f ratio wide band to make sure it wasnt leaning out. With 39lb injectors and 12psi of boost it was at 11.5 on the guage which was perfect ratio for boost safety.
And i used an apex safc-2 for tuning my jeep and it worked perfectly for what i was doing.
