Save your money for something else.

hmm... looks like this thread can keep going on forever and half of the post are pointing out that the udp isn't going to do anything if not something?

so is this the overall results?

Pro: rev's faster, constant track times
Con: waste $$$, no improvement

I want to get one really bad but I keep hearing that they don't give any gains

BUTTTTT

They provide more of a gain to autos Right?

I'm pretty sure people who say it revs faster with a UDP are talking about revving in neutral. That is not surprising, since then the UDP is a noticeable reduction on the total rotating inertia of the engine and accessories. But once you are in gear, the UDP's and accessories' inertia become an insignificant portion of the total mass that is being accelerated.

ECU is a great power mod but a lil too much for someone just getting into the tuning of the maxima. id say start off with cheap mods like intake, Y-pipe, UDP, Cat back maybe.

they wouldn't do it again not because of the low price but because the Org has too many members with not enough $$ who think it's ok to join a gd and then not follow through on a commitment.
