Well, I decided not to join the last group buy because my SHOwagon already has a chip, but I'm really not satisfied with the programming. It was installed when I got the car so I have no idea who tuned it. Shifts are soft and a knock is sometimes noticeable under load (possibly because of the chip?). I'll have to run a 0-60 with my g-tech to see how this vehicle compares to the '96 running the AmericanMotorsports chip.
Anyway, what is the estimated total $$$. If I knew this x-cal would improve the drivability of my vehicle I'd say sure, but I guess the only way to know that is to try it ... right?
