I'm trying to find out what exactly I need to order to be able to scan and tune my truck myself?? Is it this: VCM Suite Pro w/ #01 Silverado & Sierra V8. 02 Silverado & Sierra V8. +Enhanced IO 1 Pigtail. And should I get the 2bar or 1bar SD

 

www.efilive.com

 

I already know about efi but its $50.00 more and does the same thing

 

I would get the 2 bar......

 

Any particular reason!!??

 

2 bar is for boosted applications. They have some info for it on their site also.

 

Now that brings it up to 900.00 somthing, does efi offer it for less with the same capabilities??

 

HEY!?!?!?!?

 

Why do you need 2 bar?

 

I dont know if i do or not thats the question!! I will have a turbo later on but more importantly I will have the n2o real soon!!?? If all 2bar is used for, is to bypass the MAF, then I don't need it cause Id rather tune with the MAFS anyway!!
