You have to remember also, tuning is a process. You are taking components and replacing them with more powerful counterparts, you can't always expect everything that works in sinc with those parts to accept the change. I've owned my car for a year and it hasn't run right even once after dumping 7 grand into it. You're preaching to the choir, it is VERY frustrating.
I'm holding out for that day when I'll get everything to click and it will be the car I hear it's supposed to be. And if there are anymore huge monetary setbacks, then there is always plan B... "Accidently" totaling the car.
