Drieveability is enhanced to say the least. Spool is good when compared to the stocker. If you have enough fuel hang on. My sons says when the turbo lights so do the tires if you are pushing it.
Currently he set it up to run about 12cm at the minimum and that spools almost instantly and tops out at 38 psi. Hook up the controller so it opens up to the max about 33 cm or so and boost maxes at 32 psi. Need to get some EGT readings across the rpm's to see where its at but from what I see on mine they should be good unloaded. Loaded is going to a bit different but I think it should be tolerable.
The setup is on a 93 2x4 dually that has a better TC installed. When he drove the 92 home he said the difference is blatant, like between a Porsche and a VW. :-laf
