i got it tuned by doc at efi alchemy. results.... well.... she put down 169 hp and 190 tq. i know right. alittle on the low side i think. so we started lookin around at it and came to the conclusion that one of my spark plug wires has got to be bad. they tuned a stock 4.3 with a cat back and it made 150. we even changed the plugs between pulls and that was 10 hp. lot left on the table. so im changing my wires, and headin back for some street tuning and more dyno tuning. we just ran out of time. they close at 8. i left at 9:45. even still the truck feels a TON better. efi alchemy is a great shop. doc is the man.
