Okay all,
I have my 2006 silverado 5.3l sloppy stage 2 camshaft, no cats stock converter 89 octane fuel speed density tune.
I'm experiencing a "dead" spot on lite acceleration fuel trims will be around 12.5-13.0- then spike up to 17:1 and commanded jumps up to about 15. for a few seconds then comes back down and runs fine. I have attached the Data log file and the current Tune in the truck. problem occurs at the 7:14 mark of the data log
Any help will be greatly appreciated. Fairly new to HP tuners but have been able to do a lot to the truck with some good results on the street.
