I recently evac'd and charged a '91 16v car that had a dealer 134a conversion sticker on the strut tower with 32oz (as indicated on the sticker) and high and low side pressures were both through the roof, continually bouncing off of the high limit switch with the aux. fan wired for high speed.
Evac'd and recharged to 16oz and pressures were closer to normal but still not quite right, suction a little low and discharge a little high. Vent temps were decent.
