please give me some pointers on this tune. it runs great under normal driving but it falls on its face at 3800 rpms to 4200rpms at wot for just a brief second then picks back up. it smells like its leaning out at wot. but smells really rich under normal driving. it feels like its holding back for what all is done to this motor and trans it should run stronger than it does. I am new at this.. truck tune tweek.hpt it has dart pro 1 heads 625/625 234/242 109 lsa cam 1.7 rockers. long tube headers 4l80e trans trans go shift kit and all of the best money can buy components, 3000 stall and 410 gear. 39lb injectors and low profile sheet metal intake.
