What tunes should I use? Need to turn off AFM
I am looking to get a tuner like superchips or bullydog so that I can turn off my AFM 4cyl/8cyl mode. I do a lot of city driving stop and go with a load in the bed and I am completely sick of dealing with the engine bogging in 4cyl mode then clunking to 8 cyl. Any tips or suggestions would be greatly appreciated. I also want to stick with using 87 octane and maintain a descent MPG.
I have a 2010 Silverado LT 5.3L V8 with a flowmaster and K&N Full Intake.
