You can try your best to do what you think is good for your car but you never know what's going to happen. You should have never put anything on until it was ready to be finished. I hope that everything goes well for you but seeing as how you're treating it now, I am worried for your future. I will repeat everything everyone else has said...

TUNE TUNE TUNE TUNE TUNE. It is rediculous to EVER and I mean EVER run a car that is untuned, unless you are on your way to the dyno or currently in the process of street tuning. I've had a turbo D series, I've played around and I have spent money. And I can tell you that the single most important thing you can ever do to your car is to make sure it is TUNED.

my 2 cents.
