Currently trying to tune my 02 Silverado 2500hd and although iv'e watched goatropegarage and multiple other MAF tuning videos im still at a complete loss. I'll take the truck for a WOT drive but it has almost feels sluggish between 2.5-3.5k. i keep Paste special % -halfing my AFR Er but i seem to be just stuck in a loop with the calibration testing. is there something i missed or should i just keep driving and modifying the tables. Thanks you guys i don't want to bug but desperately needing help. any chance someone can just take a look and give advice?
