So I've been injured for months (if you break your scaphoid, get the screw) and coping by working on my truck. Last month I replaced my Icons with Kings. This month I'm working on my engine:
2008 4.0L 6-sp Manual
TRD S/C, no ECU re-flash
APR X-1, cam gears, t-stat, Tta40.03A.F3_425.01.AprCal
Doug Thorley L/T headers
AFE Stage II CAI
URD 2.825" pulley
Dyno'ed the truck before a map change and smaller pulley on a 4-wheel dyno @ 6,300' elevation: 190 wHp, 246ft-lb (I know, sounds low to me too). I've been working with David at APR and there might be some improvements still to be had on the engine management. I'm curious about the 7th injector. Does anyone have experience with the 7th injector on a supercharged 4.0L? The extra injector would probably warrant a Walbro 255 fuel pump kit from URD. It seems like adding some fuel before the roots would really help cool the intake charge, increase efficiency and ultimately increase power?
I installed the URD pulley last week and that made a nice improvement I could feel. Don't get me wrong, the truck drives great. Just wondering what other engine mods I should do that won't cost too much at this point. The wife is getting sick of my truck, ha hah.
