How can i up the performance of my truck, i have a 92 mazda fuel injected 5 spd reg cab, and want to increase the performance, i already have an K&N filter, got rid of the factory air box, mounted the filter lower in the engine compartment for colder/ denser air, put 40 series flowmaster muffler and a 2 1/4 high flow catalyic converter. Would a MSD 6A boost my performance?? what could i do??
