[QUOTE="CurtisF, post: 313039, member: 829"] Well I'm just going to keep chipping away at the myth that it's a bad idea to run larger injectors on PMR's as a daily driver. I never really intended to use that tune I ran for emissions testing as a daily driver, but curiosity got the best of me, and I've been driving around town just in that tune. Peak boost at WOT will juuuuuuuust barely crest at 20psi, so it's pretty damn close to stock levels. Feels quite a bit like a bone stock truck too. So for gits and shiggles I took a rolling WOT run straight up a long hill near my home. Granted I live at about 6,000 ft., so this was at a decent altitude. The run went from about 10 mph up to about 75 before I let off the pedal. All of it going uphill. My pyro gauge reads in increments of 50 degrees. Peak EGT's during that run had the needle stopped dead between the 900 and the 950 degree marks. Seriously, a WOT run at high altitude, and all I could hit for EGT's was 925 degrees! Stock injectors on stock tuning can't even get nearly that low on the same run, and I tried that same hill MANY times with various mods and tunes over the years. I was already impressed with the low EGT's on higher HP tunes, but I was shocked at the ridiculously low EGT's at stock-like power levels. [/QUOTE]
