I have the use of an original AMBrc DP transponder for an upcoming meeting.

However, I've just noticed there are products available to boost the power to the transponder for 4 cell set-ups.

Has anybody ever had any problems with this transponder in a 4 cell car?

Also, if anybody knows if an LRP ICS Digital is ok to do 4 cell modified for 8 minutes that would be a help.
