Im installing something similar to gm stage 3 it includes the GM pcm (already tuned for stage 3), 2.8 pulley instead of 76mm and or 3" pulley, and 42.5# lucas injectors. What HP/torque will i be pushing, how many pounds of boost should i expect and what other supporting mods should i add along with this? ty for any help. oh and also i dont have the dual pass intercooler plate will that be a problem?

 

damn a 2.8 on 42.5 injectors...your prlly pushing them injectors a little hard

 

Cooling mods. cooling mods, cooling mods.

 

you need some 60#s brotha

 

The stage 3 tune is almost identical to stage 2. The stage 3 just includes a tune for 50 dry shot and high octane tune.

So without the spray or HOM activated you will run pretty much the same as every other stage 2 car with a 2.8 runs.




Get the spray, it will be worth it if you already have the tune

 

Don't put that 2.8 on there though.

 

the reason i bought the stage 3 setup is cuzz i bought all the mods mentioned for a total of $250. figured what the hell . so anyways i cant afford 60#`s right now so will my 42`s be ok for the time being?

 

You are going to need a full exhaust 2.5" piping, a 2nd heat exchanger and the dual pass set up. Do not run that 2.8" on there the lowest I've heard runnin safely is a 2.85 and he has alot of supporting mods. The stage 3 tune is alot better than the stage 2..I've felt both. It would be wise to get meth so you can run the HO mode and for cooling aswell. Then after a few weeks you'll be over it and then you'll need spray.
