in my quest to figure out this tuning gig ive made changes to the TM and my shift points.im having a issue when the weather is cold out tho.the tps will not go above 32% even when i have it floored.i have been through my tune a bunch of times and dont see that i have adjusted something that would be affected by the temp. truck is a 2007 silvy classic 5.3.
thanks for the help andrew
