No tow vehicle allowed for the Street Diesel (2.8) trucks??? Is that right?? why in the world, if so?


C-ya
 
I think with the tow vehicle, they mean towed on and off the track, across the scales etc.

Well being you run a DMAX, your probably thinking that every DMAX comes with its own tow truck. :poke:

Like I heard the other day 95% of all Dmaxes are still on the road today....



The other 5% made it home!! LOL

So does this mean they are measuring the inducer bore or the compressor wheel or Both?

Very interesting rules, how do you detect if it has been modified? Provide the OEM part number and then show the spec sheet on it?
