5.3L Hypertech for the TB yet?

[03TRAILEXT]

Why? Whis is the TB and envoy any different than another 5.3l truck?

I'd check out Westers for the 5.3 V8. He has done some great things for that family of engines, especially in the full size area. I'm pretty sure he has one for the Chevy SSR, isn't this the same engine? His tune is custom, so you don't get a generic program. And he has a money back guarantee. Now if I could only get one for my 4.2L I6.......

Thanks I will, the only drawback is the price. Usually used Hypertechs ca be had on ebay for around 200 or so.

I have a 2003 Envoy XL V8, and use the Diablo Predator . It works great, and gives many more options than the Hypertech. I also use a True Flow intake which works very well in case you're interested.

I'm also using the GMS MAF off my last 2000 GMC Sierra (same model as any GM LS1 Truck)
