hello fellow lightning owners.. i just bought an 01 with 85k miles. Love everything about it.. I am have one issue though. The truck shifts fine at normal throttle and firm at half throttle, but at WOT the truck does not shift... It looks like it may have previously had a flash tuner but i'm not sure... I am thinking about buying an sct tuner and trying to adjust the shift firmness/ and shit points... Has anyone had similar issues. Any advice is appreciated.. thanks - harry
