my tahoe needs help. i want to run a custom exhaust but the stock cats make it hard to get good performance. i can upgrade to high flow cats and run a custom made exhaust. flowmasters are fine but what about true duals out the back? i see everybody talking about the dual inlet single outlet exhaust. i want my hoe to breathe.
has anyone heard about gm's HT383? supposed to be a direct bolt in replacement for the 5.7 vortec. all fuel injection, intake, and sensors are supposed to hook right in. anyone that has this motor please let me know how it is.
lastly, what about computer mods? which works best? i'm looking at jet's power programmer, but i want to be able to reprogram my prom chip and do more than i think the power prog. is capable of. does anyone know of a pc program that would tap into the stock comp? thanks!
