The adjustments that go along with the transmission modifications you have (unknown to me) can be taken care of with stock shift pressure settings.

You can get a decent amount of performance out of your E99 truck. You will never see an additional 140 horsepower though (you wouldn't with a 99.5-03 truck either) but it will run really well.

im sorry i should have cleared that up i meant get the better stock settings of say a PMT1 plus your tuning. basically my tranny mods increase line pressure to firm up shifts and if the chip increases line pressure too the shifts would be extremely harsh. and what real hp/tq gains will i see from this chip? i know the early 99 is different from others. (excuse my ignorance im new to this whole tuning deal)
