so i mostly have everything. all i need is 42lb injectors, colder spark plugs and tune.
my question is if i got my tune from zzp, could i have them send me a HP file threw email. then i need to find some one with a hp tuner right? also is there a measure ment for the smaller sc pulley cause i now it has to be perfect with the other pulleys so the belt isnt crooked.

 

Your post is kinda hard to understand. If you are gonna have someone load a custom tune on your car, then you are better off just getting a custom tune done in person rather than a canned tune. If you have the stage 2 belt, then you can run the stage 2 pulley, 3.0,2.9,2.85, etc...doesn't have to be an exact size. Just has to fit the hub you are using. But I wouldn't go below a 2.9 on 42s, espeically on a canned tune.

 

so like having trifecta tune it instead of zzp? ok say if u removed the pulley, now you have to install the hub. how far back do i need to put the hub. is there like a bulge that wont let me push it back, or would i need to measure how much space there is from the sc to the hub. if that makes sense?

 

The stock pulley is pressed on. No hub. To take it off/put new pulley on, you will need a pulley puller like zzp sells. Makes life alot easier. You just need to make the end of hub flush with the end of the shaft. Don't need to measure anything.

 

GM stage 1 kit:

injectors
tune


you dont have mostly everything. GM Stage 2 kit comes with:

belt
injectors
tune
pulley

if u dont have the tune or injectors, all u have is the belt. Just get the GM stage 1 kit, a 2.9" pulley, and have a dealership flash it.

 

i have the
belt
2.9 zzp pulley hub
injector harness
i need
injectors
spark plugs
tune.
so the dealership will tune my car for me if i put everything on?

 

ya, but maek sure u buy the GM injectors. Why the hell do u have a wiring harness?? Anyway, install the injectors, pulley, and have it towed to a local dealership for a stage 2 flash.

 

they will tune your car if you purcahse the stage 1 or stage 2 kit from GM..they wont tune it unless you buy those two kits. Yes, if ZZP send you a tune file than you will have to find someone who has HPT that can flash the tune for you. Injector harness is most likely for aftermarket injectors that he plans on buying.

 

well i can use my injector harness but i just found out i can have my stock injector harness if i got 42lb talk about a waste of money but. how much do people charge to get my car flashed from the HP tuner.
