Max boost for 2 bar map?

[Fast SN-95]

I have a FAST system and I'd like to keep the 2 bar map for driveblility, but run 20-25psi of boost. Will this break the 2 bar map sensor? Obviously it won't read more than 2 bar, but I figured I could adjust the top row of the VE table for the added boost. Has anyone else done this? How is part throttle driveability with the 3 bar? Doesn't seem like you'd have much resolution to work with.

Thanks.

If you were just a little over the range of the 2 bar sensor I'd say go for it, but you are pushing it with 25 psi. A 2 bar is only good to just over 15 psi of boost.

With a 3 bar you will lose some tuning resolution but I've tuned several cars with 3 bar sensors and they drove around beautifully.

Thanks for the info Craig. Looks like I'll be going with the 3 bar.
