Here's some back ground on my 2003 Souper Doody: 104K, OEM head gaskets/bolts, new oil cooler/coolant filter, blue Spring, SCT with SRL as DD, 3.5" down pipe/4.0" straight pipe, "home made CAI", ~4" lift w/35" BFGs and 3.73s, Pro Comp traction bars, rebuilt 5R110 with shift kit (thanks Edge!), 2004 intake manifold, Banks Techni-Cooler.
I was looking over injectors and I have a few questions:
Are the MPG increase claims true or a smoke screen to get you in?
Considering I want to keep my turbo, would 155cc injectors be a better choice?
Is it going to smoke like a freight train with larger injectors?
(I would get an injector tune to match.)
The fact is, my truck makes plenty of power for me as it sits. From this point, the only other bolt-ons will be for MPG increases. Let's face it, 13~14 mpg in town at 4000 ft isn't that bad, but it could always be better. Or should I look into an MTW hybrid to make up for the thin air here?
Given the big bucks for injectors, would I be better off just getting a set of 4.10 gears to correct the speedo/shifting? I mean, I have seen guys put 35s on a gasser, get *** mileage, re-gear and get that mpg back.
