Another of the worst I have seen for custom tuning

In this case a LS1 with a A4 trannie was installed in a old Chevy Nova.

Owner has had vendor Vinci custom tune this several times

Engine does not run right and the trannie does not work when manually shifting will not change gears.


One thing totally not acceptable is you notice they turned off about every DTC error code to hide issues so that owner never knows when a problem occurs
As seen they unckecked the DTCs and told it not to report any of the errors making it blind to any use of a OBD-II scanner

More to come as I take this apart and fix all the problems


Shown is just a small amount of DTCs turned off.
