I can undersand your dislike of the OE shift on the truck. The shift performance is night and day different on my Envoy after the Vector tune.vortech said:I have 3 I-6 tunes modified from guys over at the HPtuners forum. Mainly looking at attacking the **** tables for better kickdown for more pep in city driving and on the highway. I find the factory shifting is very lazy.

So you are talking about the table " Base Shift Pressure vs. Torque vs. Gear - Performance"?When you say lazy shifts, you may want to raise the shift pressure tables to make them firmer. Is that what you are asking?
