I know, I know. I have a new toy and am asking a lot of questions. Bear with me, please.

Any of you with the X-Cal 2, have you gone in and tried adjusting your shifting? I'm currently running the 87 tune and went in and checked where it was set, 0% for all shifts. I noticed you could increase by as much as 25%. I'm interested in making the shifts a bit "snappier". Is this the only parameter that needs to be changed or do you change the miles per hour settings also?

Thanks in advance for your input.

On my track tune, I have added 25% to my shift pressure. As for adding a MPH or removing a MPH from the shift schedule, I've only done it for the track. I think I added +2 to my 1-2, -3 on my 2-3 and -2 on my 3-4. I need to go verify, and the changes are usually dependant on your trap RPM at the track.

For daily driver, I would be careful. I jacked my shift pressure up to 20% by mistake (monday after a track visit) and in down town DC traffic, the car was jumping forward on shifts. Had to be very careful.

I usually have 20%-25% on the first two shifts and 5% less on the last two. 25% is a little much on the 91 tunes. I have experimented with adjusting shift changes up in MPH. If your mods are for midrange this may be a great thing but for stock it's not that useful.
