Sure it's been asked many times but I can't seem to find a definitive answer
I have a stage 3 1990 sapphire that I'm restoring and want to take the power and reliability to the next level.
Currently running dark greens with rs500 cooler arp stud and nut head bolts group a head gasketand the head ported.
I want to upgrade to wasted spark and have options for anti lag both I'm sure the l6 ecu could be upgraded to manage but at what cost?
Would it be cheeper and more flexible to go for stand alone management and of so what are your recommendations?
