Get the ss/sc injectors first you really can't do any power tuning on the 2.4 since the injectors are maxed out stock.

 

word to that. i mean rite now me and ^(lol) have done a tune on my car. def get the injectors. i think i was at 98IDC at 6500rpm. def need bigger injectors.

 

What does it matter what they did to a GTO? Your car will not see a drop of power without an injector swap. $475 is a good price for a dyno tune, but expensive overall.

 

I didnt plan on getting injectors but should i get them some guy wants to sell me some for 50 used 2.0 5000 miles on them. what do you think..

GRAB EM.. and get the right harness, then tune.
