well since i did the injector swap and i just looked up that website. it doesnt seem legit to me. what happens if they fail then you cant send them back cuz you used them already. heres the site i got my harness from this one IS EXACTLY THE ONLY THING THAT WILL WORK. 04 cavilear 2.2 ecotec engine.

if it doesnt work. than heres the exact part number go to the dealer and say here i need this.

15411879

its about 60 bucks with tax and shipping but its the only harness that works and its plug and play. and if you put in bigger injectors please tune it as soon as you do cuz you cant even start the car without itl flood out. but that harness will work. anys qs let me know or pm

ok well how will i get it tuned? do i just buy a hptuner or do i take it to someone? and will it help me get some more hp and if so how much more? thanks

 

well me and wickedss2005 did the work and he did the tune i had a save file from someone elses but thats not the route to go. if you have the money you can buy hptuners but i have no idea how to use it just dont erase the cars entire file lol. um or you can save all that money. take the injectors and the harness to a good reputable shop and say here put these in with this harness and have them dyno tune it preferably dynojet. and theyl probly adjust the afrs and tell them to up your rev limeter to 7k and your speed limeter to 145. anything else il be glad to help.

ryan.

p.s. what you should do is spend the 400 bucks and have it dyno tuned so the afrs are just right and you squeeze all power out. but if your doing just injectors buy a few more parts and then have it dyno tuned. if you save money and spend it on everything i have listed in my sig you should be good then have it dyno tuned. everything after that is either turbo or sc.

Injen CAI

CA stainless steel header

XTS stainless steel DP w/o cat 3.0" & going to shop and getting it opened all the way 3.0",already got muffler on it
