Me: Indy Subaru master tech
Truck: 2018 Silv 5.3/98k/well cared for/my personal whip
Situation: #7 lifter is doing the typical, torn down
My Thoughts: I do not care about max power, bought used, afm is now disabled however too late. Cam is FINE....Can I just cheat and do a non afm lifter kit and trays?? I know its not the perfect scenario however this truck is literally my home depot truck w/ some small errands.....Will it suffice, I know I should do the cam and so forth however not want I need. And a good kit/source would be very appreciated.

I've already bought the adapter harness and it was supposed to be plug and play with only a little adjustment on the tune but so far I haven't had any luck at all! can someone please help me out here? I know that its been done successfully by someone somewhere out there! I have the old style TAC with traction control and I kept my factory APP. Please Help!
