Hello everyone, I am considering getting a tuned ecm by Nelson and was wondering what all i can expect from it. Also will it have to be tuned on 93 oct for best results or can i still run 87?
This is all for a 07 tahoe 5.3l with intake and exhaust.

Forgive me but i am new to this, but always up for suggestions and learning stuff.
Thanks alot

 

should be able to get tuned for 87 and still get a good gain. You can look into wheatley as well may be a little cheaper and people have had nothing but good things to say about his work.

 

Both are sponsors and both are very reputable. I would stick with the 93 tune for best results for your money. The difference is only about $5 for a 26 gallon fill anyway, the performance gains will pay the difference.

 

Ok, Ill check wheatley and do some research on theirs too. Has anyone actually dynoed in and seen the actuall gains from these tunes?

 

lots of people have, sure. Expect 20-30hp over stock, add a few mods and it helps even more.

 

Jeeze! thats alot. But yeah i need something to wake this truck up.

thats the way to look at it ...NICE

 

i would drive to san antonio and let allen do a street or dyno tune!!! by far the best!!!!!!

 

I live within driving distance of them both. However, I'll never buy from them solely for the fact that they lock their tunes. I haven't quite figured out why, but it was probably the only thing stopping me from giving them $400 of my money.

For most this doesn't matter, but for some(like me) it's important.

 

Well i would drive down there and have him tune, it but time is tight so thats why i considered getting the mail order pcm.

What do you mean by locked tunes?
