<p>[QUOTE="prerunner404, post: 5290394, member: 69315"]Well motor had 100k on it when I put it in and I'm not sure what the status of the injectors put in were.

Would run fine on flat ground and do what I needed it to. The truck did have a stumble I'd say. Would almost act like it had a miss when pulling a hill when I was into the right pedal and I could feel a surge if I let the Rpms drop below 1400 rpm so I felt like I was always pushing the truck hard up hill to keep the rpm up. </p><p><br /></p><p>From just the short bobtail ride today back to my garage today I could tell the truck had what felt like 100 plus more hp and flat out got up and ran. I could also tell the turbo spoiled much quicker as well. So that tells me the fuel is now there to spin the turbo like it should be spun. I litterly went from 5th gear getting onto the highway and ran all the way up to 10th gear and was doing 75 mph in like a 1/4 mile. </p><p><br /></p><p>I'll know more tomorrow how it does when I hook back up to my trailer and really know come Thursday when I pick up my load. </p><p><br /></p><p>But from what I've been told and read I have the right combo now with turbo tuning injectors and manifold. Only other thing I could do for more power is a 4912 cam ( I think that's the number) and that would be the extent of what my motor could take and still be reliable.[/QUOTE]</p><p><br /></p>
