Man, I'm sorry to say it, but when I first read your post I was laughing my ass off imagining all that whack shit happening.

For the hesitating, I would check out fuel curve in DSMLink. You will be at like -32% for the entire fuel curve and then it will lean out more as you go into your upper RPM's. Check your A/F ratio and make sure you are not running too lean or rich. Mine was too rich and caused some weird hesitation. Leaned it out like 4% and it cleared that up.

Glad you kept the turbo. Have fun with it, enjoy never really using 1st gear again.
