X2. It's not the modified TB that causes a loss in mpg...it's the brain telling the right foot to play with right pedal more because of the increase in throttle response and hp. Control the right foot and the increase in mpg will be there.

 

I got a performance increase but a mileage decrease.

Say what you will but that what happened to me and I'm just sharing my own results. Ive seen others say the same

 

ok forget tht mod but what about the keg mod wat will it do for mpg??

 

Probably won't noticeably change fuel economy. You are just shuffling the power band around. That's it.

 

More power down low means less engine strain at lower rpms. So by my thinking, the kegger mod would cause mpg's to decrease. Just a theory, I left mine stock.

 

do the plemum gasket fix screw the kegger mod you will lose low end tourque your motor was bult to b a truck motor

 

ya ill prob just skip the od sounds like something i would screw up anyways, now for the plenum fix ive read tht i can just reuse the stock plate but get shorter plenum bolts, where can i find shorter bolts

 

Any hardware store. Grade five or better. Or, just pick up some washers to use with the stock bolts. Don't forget the Blue Loc-tite on 'em.

 

I've also read that you can cut the factory bolts down a little bit since they are not TTY bolts.

 

The bolts are NOT the issue, but why cut the bolts when you can go buy 15 grade 5 bolts 1/4-20 1/2" in length for about 2 bucks.
Intake bolts are not really TTY either when torqued to a whopping 12 ft lbs, while at hardware store just buy some stainless bolts with stainless lock washers, you can reuse them over and over.
That way when your steel plate pushes the gasket out you will not have to but intake bolts again...
