[QUOTE="Charles, post: 1307916, member: 103"] Bone stock PMR. Stock 4R. The only changes to the truck are the intake and downpipe it came with, injectors and 38R. The engine I'm not worried about right now sans some kind of fluke problem unrelated to the power. Anything can happen, but I'm not expecting it. The trans I hope I have in a safe spot, but wouldn't be surprised if it popped. I lift on the shifts... Definitely not even close to full power shift capability. If it was held to the floor I would not at all be surprised if it popped before you made OD. Either the trans or converter one. Stock converter too of course. I let it lock in before I roll on the throttle, lift, then back in again on every gear if I'm trying to move out. Anything under about 75% throttle it does fine, really crisp and clean shifts actually. Amazing what a PCS can do. The pressures are maxed out though. Temps are okay so I'm not too concerned but this is definitely the first time I found myself in single digit duty cycle territory. Only real issue I have with this truck is the driveline vibration it's had since I bought it. Never had a truck with a two-piece driveshaft before, and I don't think the previous owner got it right when they lifted it. I will eventually have to learn how to properly setup a two-piece setup and get the carrier bearing height and angle correct as I suspect that, phase, balance or a combo is the culprit. Definitely hard to enjoy a power pull on a PMR engine with vibration under power though. Perks up all the subconscious alarms in your body about this being wrong, lol. [/QUOTE]
