I was told by MPS that they can only set the carb back to OEM specs because the computer pretty much runs the carb. What could i do to get more power AND better fuel economy out of the carb?

IF youre keeping the CCC system

Leave the primaries alone - the computer will control those, and thats is where the fuel economy is.

On the secondary side, open the secondary air flap open distance by trimming the limiter tab, loosen the secondary flap spring to a setting of about 1/2 turn, put richer secondary rods in. Get a primary pulloff that opens in about 1.5seconds.

There is a big improvement to be had in the timing curve. Get a chip for your ECM from Hypertech. They really do work.

Just ordered a ZZ4 HO intake. Hope to get the car in the garage this week and the carb sent off to be rebuilt.

Anyone know what P/N gaskets i need for the intake?
