My friends 97 1500 is much happier with Nelson's mail order tune in it. It has a Comp 212/218 .488/495 on 112 and Hooker comp headers and duals. Plenty of bottom end to roast the tires(tire) too. Idles almost too smooth now. Hardly any cam sound at all, not that that's a good thing. Gone is the part throttle miss when cruising that I thought would never go away and the random misfire code is no more also. Truck runs much better all around. Time for a shift kit now. The newfound power is really taxing the 1-2 shift.

 

what motor?????
