Look to the banner on the right side of this page and you'll see Nelson Performance, Wait4Me, TBYRNE motorsports and Texas speed and performance. These are sponsers of this forum that offer PCM tuning.
Please forgive me if I left anyone out.

 

I have a wait4me and I love it. I pull a 6000lb ski boat in the summer and I have no trouble in the least bit. The tune will set you back 158.05 which is about $250.00 less than Nelson. If you do internal mods or forced induction, then you would be better off with a dyno tune.
