U have an LSJ sir. I can tune you too when I get back to Charleston this fall from my deployment.

 

sweet, hopefully when you get back ill also have just about everything i need done to it and it would be ready for a tune.

 

Have at least a 2.8" pulley, 60# injectors, and a AEM UEGO wideband ready and you will be in for some fun sir.

 

Use the histograms if you dont have a wideband

 

Explain more please. Never tuned that way before.

 

the only tune i will really need is the ecu tune that you get when you purchase any stage upgrade which i will be purchasing zzp's kit, also while on the subject of zzp do they actually make quality stuff (no offense to zzp) im just wondering because if im goin to be dumping around 1300 into their products in the next couple months i just wanna be certain im getting quality stuff, especially their version of the stage 1/2 upgrade. thanks guys

 

heres the thing..... if you have a tuner then you do not buy a "stage kit" which comes with a tune you would just buy whatever you want and then your tuner tunes it for your application.

the advantages you have with a tuner over a box tune setup are:
after you pay them they will tune you any other time for very little money or none at all.
you get a tune specific to your car which can be both safer and create more power
if you dont like something you can get it changed. e.g. too much boost in first gear, you can tone it down how you like it.
you make new friends

 

so killin what your saying is to just buy the smaller pulley, belts, injectors, and the harness for the injectors and just let 2k5SS/SC tune it. that would probably be better for me to since cash flow is a little short.
