ty sir. i'm quite aware of that. i also doubt map/maf can be run at the same time. i was just using it as an example of what is monitored and whatnot.

 

civis Si uses map and maf...

 

well then...
how does that work? sensors before and after the intake?

 

Can someone tell me why there is so much negative feelings in regards to using piggyback modules? I have had very positive results wit mine for over 2 years and at a relatively inexpensive cost when compared with the price paid for an average priced name brand intake or axle back pipe.
