I installed my Nelson tune today. I would have to say that at WOT it is about the same as the Predator, although I know it takes about 500 miles of learning to get the full effect of the new tune. At part throttle it seems to have a LOT more power that the Predator. Overall I'm very happy with it.

I am throwing the P1336 code. I know I have to bring it to a pro or someone with HPtuner to have this fixed. It seems to idle fine until I check it out with the Predator. The idle speed is jumping around 15-20 rpms and the timining is jumping around 5-10 degrees. When I hit WOT in 2nd, it sounds okay but in 1st, it sounds like a bad knock but I'm not showing any KR. I know I have to bring it to a pro or someone with HPtuner to have this fixed.

My question is, since it's Saturday and I probably won't be able to bring it in till Tuesday, how safe is it to drive?

 

Your idle will take about 50 miles to relearn and get smooth again.Your timing will jump around at idle until you give it gas.

 

Thanks, I'm still learning about this stuff.
