Tune After LT install? Could someone tell me if I REALLY do need a tune after my LT and y-pipe install. How much hp would I gain. My car is a 67k mile A4 Z28. Help gas mileage any? If there is already a thread on this please point me in its direction.

I have been riding around with out a tune on my car lid long tubes and trueduals. I got a base line tune just an ls6 map deleted codes, i drove 10k untuned and now drives alot better all around.
I'm glad I got it tuned. Overall drivability, gas mileage, and performance all got better with the tune. It's worth it. How much will you gain? Well that depends on how your car reacts to having longtubes on it. My car was pretty rich before my tune, once my tuner leaned it out a little bit, the car definitely did seem to pull harder.
