I haven't driven it so I'll have to use a program to calcuate it. Plus, his instrument cluster is for a gas truck, not a diesel, and the tach reads around 500rpm off. He has been using his edge cts to monitor RPM's. But he never gives an rpm number when he calls me telling me what it is doing. Haha
It has a 4R100 trans, and OD is .71. So it's around 1558 since the tires are worn it could be a little more. That is well under the turbo RPM range. He's working on getting different tuning to change the trans shift points, but that isn't going to help. It needs different gears or smaller tires.
Part of the draw backs of going with an aftermarket turbo.
