2.5 or 3 bar map sensor?

I will order my Eurojet SMIC next week, but don't know which map sensor to go with.
2000 Jetta TDI with auto tansmission, stock turbo, PP357 and Aligator tuned. (PP357 added after Aligator, so will retune it.)
I want more lower end torque and better economy, and will definitely get RC once I get one extra ECU. So which sensor would match both tune?Thank you

RC and Alligator can both be used with either the 2.5-bar, or the 3-bar, MAP sensor. You won't want to put the 3-bar sensor in if you have a tune for the 2.5-bar sensor, as it will add ~7psi to the boost levels.

The sensor must be matched to the tune. If you're running Aligator (or RC, for that matter) for a 2.5 bar MAP don't switch unless you get the tune changed. The real value of the 3-bar is for tunes running more than 22 PSI. You're probably not going there with your stock turbo anyway, so why switch?

Thank you guys, I will stick with 2.5.
