I,m doing a 6.0 lq4 swap on my 2002 tahoe 5.3 4x4, just bought my 411 pcm so I can mail it to someone! I need some help on who I should send it to. What should I ask for on the programing? Keeping engine stock for now, but will add milled heads .030 if people think I should do it now while it's on the stand. I tow a 6000 lb trailer so I need low end 2500 - 4500 rpm power. Thanks for the help in advance!

 

oh boy hold on for this one! LOL

I am going to be buying a Nelson Tune later this fall. Just from what Isaw and read, I think they will fit my needs best. Everyone has their own opinion, just do your own research and see which will make you happy.

 

Nelson all the way.

 

 

pm dc_justin, he does some awsome tuning. where are you located?

 

NELSON TUNE!!!!!!!!!!!! Get the head work done to increase compression ratio now if engine is out. That will definately help your low end.

See if you can find a local guy, cause w/ a mail order tunn goes wrong the game of phone/e-mail tag sucks, its gonna be a hassel. If no one does it around you than Nelson or Wait4me.

 

dyno tuning would be way better, it could take a few tries to get a mail order tune correctly, if ya cant find any one local to dyno tune go with nelson..

 

Not a wait4me.

 

Definitely. Especially with changes to the heads or cam, dyno is really the best option hands down.
