Only go with Steeda. Check out Sparta Performance.

From what I know of them on this forum, Steeda is the only way to go. You should have a tuner so you can raise the idle a bit for the alternator.

I have Steedas in mine. You won't feel a big difference with them in, but there's something and you'll see a small increase in fuel economy. I wouldn't know first hand, but I've heard that they don't work as well in forced induction applications due to their smaller size. So maybe avoid if you plan on going with a supercharger at some point? I'm sure someone more knowledgeable than I will be along shortly to set you straight on that part.

+1 on the Steedas.

FWIW, this is probably a mod you don't want to consider until after you've done gears, a tune, and maybe a CAI, as you'll see minimal gains (they don't actually INCREASE hp, they just reduce HP cannibalized to drive the accessories belt); the primary thing you'll notice is the engine will spool up a bit quicker though low and mid-range.

As PR noted above, if you go to a Roots-type S/C (Trilogy or Eaton swap) you'll need to convert back to the OEM pulleys.

Must have tune with this

Steeda ...

As for the tune, I have one, but it does not compensate for the UDP's. My idle drive idle is around 600, but no battery light.

Not so much a tune, as bumping up the idle speed in the tune to drive the alternator fast enough to maintain voltage.

You wont have a battery light issue, just the voltmeter will show 12.5-13V at idle with it set like that.

Sits at 13V, pretty rock steady.

I figure when I get a little more done, I will get a new tune for it. I have a SCT2, so I need a tuner who can work with that. :)

Is there any other? :D

He actually did did a couple of tunes on the SCT2 that came with this DPB.
