I keep reading about the Demon tuner on here but who makes it and where can I find it online. I have been looking at the Diablo Predator for the programmer I may purchase. I understand you get more if you just have a custom tune but I do multilple tasks with my truck and I want to be able to swith back to factory if i ever need to. I have an 01 GMC z71 with 125K on it and I use it for everyday driving, long trips, and pulling a trailer. Any advice on the purchase of a programmer would be appreciated. Thanks

 

Look up Westers Garage on the net or call and talk to Lyndon, he can write the programs for the Demon and does other PCM programing that is much more impressive. You can get ahold of him at 1-888-937-8371 he is very knowledgeable and willing to answer questions and help. Why do you want to switch programs? He can also make the tow-haul button for better towing while keeping normal driving normal but with better performance. Either way Lyndon or one of his reps is the only way to go, safe, reliable, dyno tuned, and milage tested.
