Message: [QUOTE="Kind, post: 698209, member: 410"] I have noticed at about 1/4 throttle my truck seems to flatten off... So I did some data logging and found some odd numbers lol. The tune I am running is H&S 300 during data log but I noticed these effects on the lower 3 settings as well. At 38% throttle my pulse width jumps from 1.7 to 2.7 then kinda jumps around. My fuel rail pressure eventually hit 23,000 but it happened to be at 1.4pw for a only a few milliseconds. I also noticed my catalyst temps were both at 932 the entire run... no matter throttle input. My MGP never exceeded 24.3 which doesn't make sense for my triples. I am going to try my old KEM tune tomorrow to see if it's a tuner issue or something else. The trucks has ran better on the low end since I installed the MAF... obviously... But like I said it seems to top out and degrade some. Anyone have any ideas?? [/QUOTE]
