I want to upgrade my gm charger injectors to run about 10 psi on my turbocharger. What would be the easiest way to do this? What do I need to control them and what size would be good?

well they are 320cc injectors

the next best would be to use the eco s/c kit injectors which are 36lb , and the same style as the 1's for the 2.4


im using the 2.0 eco s/c injectors , and they were kinda a head ache to make work due to the length differences

anyone have a part # for those?

it is in 1 of the eco s/c threads , i forget which 1


id search for it , im short on time im at work


i did post in the thread

really the 2.4 can use the eco 2.2 s/c injectors???? any word on price and are tehy plug and play so to speak???


Thanx Charles

yes it can , and look for the thread with the part # it was posted in today

I looked up the part #. 12593904 $275.52 shipped for 4

easiest way:
Change your injectors clips to the square type and pick from a real choice of injectors.
Get a wideband (unless you have one)
HP Tuners software and go from there




Save a Tranny, Roll-on
15.3@88m.p.h.(I/E)
15.2@94m.p.h.(S/C'd)
15.5@89m.p.h.(Stock GTP)

I want to run about 36# or 42# injectors. Will My reflashed computer run these without any help or do I need something else to help it? Also I have a wideband and on the dyno the afr peaked at 13.22. How much is the HPtuners and how hard is it to tune?

With just the reflash I have run 32lb injectors.
I may be wrong but I believe the Reflash can accomadate a variance of up to 15% from stock.
With HP Tuners you can run any size injector you want.
Not sure how hard it is to tune. There is a sticky about it in the performance section .
