I've put about 150 miles and all I got to say is DAMN! Talk about waking my truck up! Allen Knows what hes doin. I'll give you a lowdown:

Before I had the Superchips programmer and it worked alright until I removed the Cats. I lost alot of lowend and the truck just never seemed as responsive.

I called Alllen and he recomended the dual 89/91 tune. He firmed up the shifts, Took some TM out, erased my rear 02 sensors, recalibrated for my tires and the best mod is turning my Tow/Haul mode Button into a "Race" button .

My truck feels great! I got my lowend back, and its really responsive, it shifts nice and firm and the race mode is sweet! It shifts really hard!
I used my Gtech for some before after tests
I know its not totally accurate but good for testing purposes
Before with Superchips Averaged: 235hp
After with Nelson tune 91 octane Averaged 272hp

Again anyone thinking about doing this should do it. Its personally my best mod yet!
Thanks again Allen!
