Also looks like there's two MAP sensors....what's the point of that? Possibly independent fueling for each bank? Or maybe two one-bar MAP sensors instead of a single 2-bar? I bet it'll be interesting to dissect the tune on one of these bad boys.

 

It looks like the one MAP sensor doesn't even go into the manifold.

 

I think only one of those is a map sensor or the one that doesn't go into the manifold is for measuring atmospheric?

 

I'd say 2 maps to compare pressure difference and possibly throw an inter cooler clog code. It looks like two independent pressure chambers of the intercooler

 

Weird, I just noticed that. Seems like it would have to be what truckmann said then, one just measures atmospheric pressure. That leads me to believe that it's going to be a SD factory tune instead of MAF. Hmm....

 

That sounds very plausible.

 

People know... but people also cant say.. lol.. othewise you'd know by now..

 

old news.........he..he... i saw this in a denali in june.

enjoy and drool!!

 

 

Thats in a truck engine bay....or not... It's sad that I can't tell
