Well I got that far, Remember that is a proto type in raw form, needs cleaning up, I do run a bigger air tube with insulation, bored 4.0L TB, custom TB spacer, accel coil and wires, NGK plugs gapped at .037, catback, magnaflow muffler and of course it does have a K&N filter. Like I said before I am able to adjust my incoming air to adjust for fuel changes. I can get my lil rig real torquey or smooth response with top speeds of 80 to 85mph. I am still tweeking to find sweet spot between power and MPG. Any do not laugh its working nice, I know it does not look impressive.
