Hummer Fuel economy Increase

[friend777_99]

I INSTALLED MSD COILS ON EACH MULTIPORT INJECTOR.THEY COME ALL IN A KIT FOR ABOUT $680.00 FROM MOPAC.

I USED TO HAVE A PROBLEM TRYING TO USE THE COMMAND START SWITCH TO START THE HUMMER. IT WOULDN'T START ON THE FIRST TRY... ONLY CRANK FOR A FEW SECONDS. NOW IT STARTS NO PROBLEM. THE MSD UNITS RAISE THE STOCK

COIL VOLTAGE BY ABOUT 3 TIMES. 50000 VOLTS TO 150000...PLUS SPARK 5 TIMES PER SPARK BETWEEN IDLE TO 2500RPM.

AWESOME!!
