Just started modding my 01 ex cab 5.3 2wd..I'm looking to do full bolt ons.and daily drive it.wanted to see witch is the best tune,tuner to go with...there's a few guys that do tunes with hp tunners. Not sure to go that route or do a different tune.what tunes are you running?..I wanna get rid of the gov.and improve the shift points .etc..

 

give nelsons performance a call, i love my tune and they have taken care of me for about 3 years no no questions asked. and its alot better than any hand held.

 

A tune in person or dyno tune will always be better than a mail order tune, given the same tuner competence. Don't mess with a hand held tuner. Although I don't know if they are a sponsor on pt.net or not, I've had some really good experience with pcmforless here recently.

 

I cant figure out how to make new post srry but i have an 03 tahoe 5.3 it was running lean so i replaced the intake gaskets and fixed that now i have a p0172 and p0175 both banks are rich it is getting like 12mpg any thoughts? I also was wondering which is better neslon or blackbear

 

there about the same, ive always had good luck with nelsons tho. id give them a call and they can prob help you fix your current problem as well.
