I'm putting this here since it's not about a Barth. We came across a 1999 Dynamax Isata that the owner just wanted to get rid of. The interior and drive train are in excellent shape. The clear coat not so good, but I can fix that. Quality of build reminds one of the Barth. It's on a P32 chassis with a 5.7 engine coupled to a 4L80E transmission. According to the literature, its an L31 engine with sequential fuel injection, rated at 240 HP at 4000 RPM and 325 Lbs of torque at 2800 RPM. The rear end is a 4.10. The thing is great on the flat, running at 1600 RPM @ 55 MPH. But on modest hills it can't get out of it's own way. What can I do to give it some more guts without spending a lot of money. My son-in-law has a 2002 GMC van with the same engine rated at 300 HP. Thanks
Jim
I'm still hoping to get Old Blue back someday but I'm running out of time

Down shift before it gets to 3000 rpm, the auto probably waits a bit longer and has a problem getting back. Might even shift at 3200, you might have the program changed. jmo
