What are you going to use the truck for? Are you using it for drag racing at stop lights or are you using it as a truck? If you are using it as a truck and need the turbo for towing, then forget about the wastegated turbos and get a turbo that will do you the most good and get a
Hypermax non wastegated turbo kit. Hypermax quality is great and their customer service is second to none., ATS customer service on the other hand will leave you inventing new words, most of which cannot be used in mixed company. I have an ATS and if I had it to do over would buy a Hypermax next time. I have one of their COwl induction setups and love the thing and will be getting one of their smoke puff limiters soon
ATS quality is a crap shoot, some folks get ones that go right together, others like me get a down pipe( after waiting over a month and being lied to numerous times) that has to be ground down a bunch to fit in, others , get downpipes that are so loose that the things won't stay in and they leak like crazy ( it's a slip fit). I wouldn't spend another dime with ATS.
If I'm not mistaken, Banks is discontinuing the IDI turbo kit and support for it so parts will not be available . ATS already discontinued support for my turbo, they are still fooling with the Aurora for however long they decide they are selling, but when that falls off, they will pull the rug out from under that model as well
Hypermax is the only company left out there that is still actively developing new performance products for our engines , it only seems right to support them
