Anyone have much experience tuning in Hondata? If so how much horsepower and torque can a lightly modded GSR (B18C1) pick up? Right now the car is needing a computer bad, and doesn't run great or get great gas mileage. I'm helping my buddy out that cannot be here right now and I wanted to find out how much power Hondata can help out from other experiences on a GSR motor.

Would a S200 work the best for tuning or an S300?

Thanks,
Amir
