would somebody help out an old guy trying to use hp tuners. i would like someone to look at my tune file and log readings. I bought this truck from a young guy who was struggling with getting it sorted out. I currently have the electric fans connected and working. Fans were coming on with the key on. Rewired it to work with the pcm. The truck seems to run fairly good but im new to this type tuning.
Mods: 821 heads with truck intake (
Cam MS-3
92 mm throttle body
6.0 not sure what model ( was told it was rebuilt ??????)
Trans is suppose to be a 4l70e that was recently built W/FTI 2800 stall
The truck runs good but feels weak until it gets to about 3500 and pulls hard to about 57-5800 and goes flat. feels to me like it runs out of cam??? but if it is a MS-3, I would think it would pull a little further in the rpms. also seems to to slide into 3-4 shift almost like its slipping for a second or 2.
Any help would be appreciated
Thanks
