4v Bolt-on Question
I'm running 4.30's and get 20-21 mpg on the highway with a Keisler T45 w/ .67 5th. Obvious mods(for me at least) where short throw shifter, built sra, JLT cai and dyno tune. The cat-back on these are also incredibly restrictive. At the bends under the irs it closes to well under 2". I gained crazy throttle response and top end power when I installed my x-pipe and pro-dumps.
