October 26, 2003Both would improve, best to do both, but to answer your question, I'd say chip.
October 27, 2003No doubt the chips will make the diesel faster than the exhaust. The point of the exhaust isn't to make it faster, but to decrease exhaust gas temps, so when you do a chip you wont heat the engine up to much.
I actually just installed a Banks 4" Monster Exhaust on my 2002 7.3PSD and it sounds different, but virtually no difference in speed/power. Now tonight I am putting the programmer to it, and I expect massive changes in speed/power.
October 27, 2003I agree with these guys probably a chip will give up better performance increase then the exhaust.
October 28, 2003I know on my 5.4, the chip (Superchip Max MicroTuner) gave me much more power than the exhaust and e-fans combined. I'd say chip it with the new Superchip (3 settings) and you'll be very pleased. Then save up for a nice 4" exhaust with a 5" tip.
