I had a '91 Westy which had been converted to 134. I added 2 cans and
according to the inexpensive pressure gauge I bought, it was slightly above
the recommended limit. Blew barely cool.
Took it to a local service provider and they evacuated the system and
recharged it and it blew very cold. Very efficient. Only cost about $40.00
for that so was well worth the investment.

at a much greater cost)
