Ok guys posting for a firend. He wants to keep gas mileage cause gas is $5.05 -5.35 a gallon.
The truck is a 2006 escalade on 26" wheels it has
Volant intake
Pacesetter long tubes
3" exhaust
Hp tunner
He wants to do a cam and possibly a small stall if it won't chew gas.
Any advise would be awesome .
