Just wondering if any one has tossed the GEMS box off the MPI turbo and installed a PCV with or without a autotune. I have a PCV and a autotune and a ignition module and I am wondering if I should put it on my MPI 190 kit.

I also went with head shim and boost switch for 8lbs and 12 lbs, I love it.. runs way better and is way better on fuel too. Went to 4rth injector and bigger volume fuel pump.

Just finished doing one, Runs much smoother and is better on fuel. Did not have much luck with the GEMS controller adn it ran pig rich before

you'll wonder why you never did it years ago. ulmer will be able to set you up with a map and everything. fuel milage improves throttle response there is no draw back to ditching the gems. ignition module you could put a stutter on but other then that don't really need it.
