Spent the weekend putting this thing in with my dad. Just took it out and runs like crap. Hesitates at full throttle, and doesnt want to ship properly. I started out with the stock tune by superchips, and yes using a 3.0 pulley. I didnt expect it to run great but this sucked. So after a few miles of no change I took out the superchips tune and added the PCMforless tune. It did run a little better but still a bit of hesitation and the shift sucks. Its like the engine is winding up with all this power but its not putting it down to the wheels. I am lost. I read Justins thread about the KR readings. I am in the same problem area here?

I feel your pain. Im in the same exact boat as you are. Did you notice with your superchips tune your truck didnt move for awhile off the line and then went. And when you'd start it, it would sputter a little and then idle fine. And now with my pcmforless i have rediculous KR. I need a dyno tune so badly. I think that is the only thing that will save us.

When do you see that much?  Is it from a dead stop and WOT?  Is it when cruising and then WOT?

It usually happens when i give full throttle and it kicks down a gear. And im not to sure but it may do it at a full throttle start. Not to sure. Im staying off the throttle for awhile.

OK i finally got my scan gauge reading knock and it doesnt look good. Im reading 7.9 KR and i can FEEL IT! Its like my truck is bogging down when i hit 7.9. How bad is this for my engine?
