So ive been forum guy since I was 14 with me first 87 monte Carlo ss(which I still have ) I'm 24 now been working in field since I was 18, all I want is honest review of 07 silverado 5.3 nnbs programmer I am well aware of cams new torque converters real seat of the pants performance upgrades, but are there any programmers that I will be satisfied with. Is there there anything with the price? Or should I just save for cam swap?

 

EfiLive or Hptuner is the best tuning software around. If you have no idea how to tune then leave it to a pro, one of the sponsors can take care of that for you ---->

 

I agree^^^^^^ as for hand held tuners I wouldn't waste you money just get a tune from one of our reputable sponsors on here and you will be very very happy.

 

Go with a custom tune, handhelds are not worth the money. Someday down the road if you want a cam or something just get a retune.
