Well, been a long while since I've been here. Had life get in the way haha. Two fuel pumps, a new gas tank, some sensors, distributor, and a baby, I got around to updating. I put the 80lbs injectors in my truck, tuned it a little, and thought I would see what everyone thinks. I drove around with 9 full size rail road ties in the bed (about 2250lbs being conservative). It runs GREAT but I'm far from done tuning it. Over the summer I'll be putting on some vortec heads, too. Just to recap what I'm running: 92 k2500, 7060 ecm, 357sb, flat top pistons, ported tbi heads with 2.02/1.60 valves, estimating 9.5:1 compression, summit sum1102 cam, 1.5 roller rockers, hedman competition headers, torker2 intake, 454tb with 80lbs injectors, injector pod spacer, AFPR cranked all the way up, msd 6al2. I had a salad bowl on but took it off because i didnt like how close it sat to the hood, need to get a cowl at some point haha. so i still have the choke tube and stock air cleaner assembly, except i have a k&n extreme flow filter lid and a 14 in filter sitting in the air cleaner. plugs are gaped out to .060 according to msd's recomendation, and running autolite plugs one step colder than stock. trans is a 4l80e, 4.10 gears and govloc in the rear. straight pipe exhaust, no mufflers or cats. no egr. thinking about getting a shift kit to put in it over the summer, too. I use the truck to haul a mud truck, and run in modified stock class in mud bogs just for fun. any suggestions for improvement, either mechanical or programming? i will say, the blm numbers seem pretty low (in the 105-124 range going up with map) in the lower rpms, but after about 2400 rpm they smooth out to 128 in every rpm and map.
