I see the HPTuners supports GMs 3.4l cars, does that mean I could tune my 3.4l 2001 Pontiac Montanta?

While we don't advertise the montana support on our orders page, the new 2.1 software and interface should recognize it.

The reason I was asking is that I thought those vans used to be there on the order page. I mostly want to fix the ridiculous transmission set up. The van famously shifts from a region of engine torque to another gear where there is none. Then it abruptly downshifts again when you keep moving your foot down because the van stopped accelerating.

I am one of the pre-order customers so I hope to see it soon and fix this problem. Then I plan to delete CAGS from the SS as my next step.
