<strong> Mine are set at +3/+11/+0 with the 6200 limit too and it helps a lot. I did notice when I was running the stock 2 3/4 inch intermediate pipe with my single in dual out dynomax that it kinda nosed over around 5700 but when I put in the dynomax 3" pipe it started pulling hard through 6k. I didn't really realize how much it helped until I tried it in tow/haul mode and let it shift early. I don't want to go any higher though cause I'm scared I'll hurt my accessories reving them so high. </strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Where did you buy the Dynomax 3in pipe?

I got it from jegs. They ordered it from Dynomax and then sent it to me. Took about two weeks, and cost around $75 shipped. I got the part number from the Dynomax website. For the ex-cab short bed it's 55042. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Wow, 7 year old thread...welcome to PT.net. You need tuning software to change your shift points
