Ok this is my first attempt at changing anything in my tune. I have 99 Ta with heads cam and stalled auto when I had the car tuned I was running 373 gears which I later changed to 410's. This did not affect the car other than speedo being off but I just put a new transmission in and would like to change some of the part throttle setting. I have Hp tuners pro, I have already saved a copy of original tune and made another copy with what changes I thing will suit my driving style better. My question is on loading the new tune. Do I import changes, write entire, write calibration only? Any help is appreciated I have probably already read the answer somewhere today but I believe its time to take a break from the computer.

 

Write calibration only.

 

Thank you.
