yes this car is great but i want more pull...i bought the car gmpp stage2/injen cold air/borla catback and the gm reflash

this is my first performance car(i think i is) and i want a little bit more
what is the first step

custom tune(whit this set-up)or replace the pulley for an 3' whit and zzp heat exchanger or install header and downpipe

i know there many post on the lsj mod but im not familiar with the forum
anyway let me know

 

header/dp combo!

 

good to read...just add this combo...no need to tune?

its 160$/eah hour to tune my car here....this is why i ask that

so i saw on thew zzp website taht they sold tuned PCM...good idea?

 

If Memory servce,
You should already have a 3" Pulley... you I see, you typed 3'... I dont think a 3 foot pulley would fit though, so I'm guessing you really ment 3" But ya, If you have GMP Stage 2, you already have a 3" Pulley.

FYI :
" = Inches
' = Feet

 

ouppsss sorry your right..

so you said that i already have the 3'' pulley..good to know...

at this time im not able to put smaller pulley with the n.42 injector and keep this tune?(even if i install a heat exchanger)..

anyway i will try a header and dp first and if i can install a smaller pulley

 

IIRC Stg 2 is 3.06. You can put on a 2.9 and keep things pretty safe. If you don't want to spend too much just get full exhaust, 2.7 pulley, 60lb injectors (80's if you will eventually turbo swap, etc) and meth.

 

great!!and no need to tune....?whit the 2.9 pulley

 

if you want more power and want to take advantage of the pulley and header and dp combo then yes i would retune

 

ok like ive said in previous post i will going to install header and dp first and maybe a zzp tuned pcm

 

you can do that but in a sense that is just a canned tune...they are good to a point
