I purchased the SCT from ID a few weeks ago with just the three basic tunes. Street, Tow Aggr, and Economy. I run the street tune 99% of the time and enjoy the extra power however, it is not tire smoking power, infact I can't even break the tires (33x13.50-18 Pro Comp Extreme A/T) loose. I read many posts about people smoking the tires from a roll on in 2nd and 3rd gear but that doesn't seem to be the case with mine. A WOT start from a dead stop only produces quicker accel, no tire spin.
Does this seem right? Does this compare with your experience running the STREET tune??
