do you have a code reader to determine what code it was? u could of easily limped the tranny which is much more likely than blowing the headgaskets. u could of also drained the rails on the 150hp tune( though i never do on mine) and that would set a light off as well and make the truck fall on its faceWell I got in it last night pulling out in front of someone, forgot it was in the 150 tune and it like lost power so I let out and engine light came on. So I pulled over checked everything, all temps fine no smoke, put it in stock liked it home. I have the egr shut off in the tune but no blocker plate could that also be an issue?
race valve takes two minutes to do, i did the shim with dustin and we did both of ours in like ten minutes. normally yes. we are just doing guess work until u pull the codesI have the race valve just not installed yet, also trans seemed to shift smooth and temps stayed normal. I thought if you limped it, it stayed in like a certain gear.
