Nelson Tune ?

If I get a mail order tune (I'm in south Fl) when I take my truck to get warranty work done will they be able to find out it's a different pcm and tell me they won't work on my truck?:hyper2:

Yes they can tell, but there is a way around that little problem, just keep your stock pcm and swap it when you need warranty work done. :hyper2::hyper2:

Eh, only if they hook up their scanner to it and read the tables. Good thing is that Nelson locks the tune so that if they do in fact read the tune, they can't change anything...

Isn't it another 150 to keep my stock one?

Not sure of the core charge. If you want, you can keep your stock PCM. If you don't wanna pay the core charge, you could get on Ebay or go to a junkyard and get a second PCM and then send that one and have it tuned instead...

the core is $55.

thanks,
allen

Thanks so the total would be $430?

Well worth it.

How long does it take for the new PCM to kick in is it instantly or does it gradually do it over several hundred miles?One more ? I've heard alot about relearns what are they and where can i get them done? Sorry about all the ?'s

200 miles or so for relearn, or to get the most power. crank relearn can be fixed by the tuner.
