i recently purchased the cobalt addiction stage 4 kit cause the advertised 65 hp over stock kept flashing and looked more and more enticing. i havent gotten it yet and im somewhat afraid to end up with a blown piston (rip). the only mod i have currently is an aem cold air intake. have you guys heard anything pertaining these kits and what would your recommendations and mods to follow this BIG HP and BOOST upgrade. i live in TX so its hotter than Satan's ******* down here. would that make a difference

the kit comes with a ZZP Interchangeable Pulley system , 2 step colder ngk IRIDIUM spark plugs , GM shortened belt , ZZP Adjustable Tensioner , 60# Siemens Injectors , Injector Wiring Harness, Stage #4 Retune

thanks

 

I'd be careful, and I would definitely get it dyno tuned.

 

I was the test car for their stage kits (all 6) I'm currently running my own modifed version of stage 6 for the last 15000 miles with no issues what soever. The out of the box tune is pretty safe timing and afr wise (new tune) but with all major upgrades it is definitely recommended to get your car fine tuned by a professional dyno shop to get the absolute most out of it. But you should not see any ill effects overall.

 

Im running a stage 5 for 2000 miles. No issues so far but i do have a custom tune

 

Meth Injection. I 'm picking it up soon and i am only running a 2.9. It will defintately help keep things cooler.

 

hell yeah man... my IAT's are down about 60 degrees... car's beastin again

 

thanks guys. this IS the big upgrade of the summer so i want to keep my car for all of it! im problably going to suck it up and get the ca heat exchanger and intercooler custom end manifold. its hott out here.

 

yeah and make sure to get the meth injection too.

 

meth is key to the motors survival at those boost levels... that's why mine is still running strong

 

meth injection is great i had it on my h23 boosted to 6 psi i think its what held my motor together for so long.

for someone who puts alot of miles on there car and just wants enough power to take out some lightly modded big cars whats suggested as far as ca stage kits?

 

Get a custom hp tune with it and you should be good.

 

Just get it and the dual pass and you won't be sorry. The HE helps too. You shouldn't need a custom tune beyond what CA does with the PCM. I've had the set up above for three months now.

 

i have the CA stage 3 with the dual pass endplate and option "B and it ran perfect, i currently have it uninstalled, but when i re-install i will b hptunning!
