Just installed the Mach 4s. I believe the truck is just as quick with the EZ Comp on 1 as it was on 5 x 5 without the injectors, maybe a tad quicker. Put it on 5 x 5 for a short burst and my-O-my. Haven't run it long on the high setting but the EGTs are staying cool taking it easy. With it running so well with the box almost off. Do you think the injector pump will last longer? The only problem is it seems to take longer for the turbo to spool up.

Happy, Happy Me
