You can either buy or make the "CAGS defeat" or just keep it in 1st gear until you get over 1800 RPMs or whatever it is. When I had my Z tuned, I got them to turn off the 1-4 shift via LS1 edit.
You have to remember that the LSx engines have massive amounts of low RPM torque, compared to a Bimmer. You can drive around in 4th at 1300 rpm and still accelerate without bogging down the engine. Of course a downshift to 2nd will accelerate oh so much faster!!The CAGS defeat plugs are available from almost all Corvette vendors, and solve the problem for good. I have had one on my vette and 94 Z28 from almost the 1st week I've owned them.
