Timing troubles, I think!!!!!HELP, It's driving me nuts
I have an early 99 with a PMT1 computer tuned by Jody. I have Jody's tunes for big oil. I can tow in 40t and 60T with more power than I had available before and no problems. Tows up hills in overdrive that I could barely get up in drive before.
Now, when I use 120 race or 140 extreme at WOT there is a rattling sound(almost like pinging), boost drops plus I can hear the truck change sounds. When I back off the throttle it stops and boost/power picks back up. We(Jody and I) have been fighting this problem for about 6 weeks. I already emailed Jody this same info.
Please tell me I am not the only one to have any troubles like this...
