I have an Dodge '02, 5.9 24V 2500 and have pretty much settled on a Quadzilla performance chip. However, there are two that seem to suit my needs and I really cannot tell the difference between them. The XZT+ and the XZT Zillaraider. To go along with either I'll get the XZT Recon gage board. Can anyone tell me what the real difference is? I'm looking for the horsepower and MPG increase both offer.

Thanks.

 

The xzt+ is the new one and adds timing along with added fueling. The older xzt only adds fueling. The xzt+ also has a usb port so you can download new tunes to it for free off of quad's website. Both however are plug in boxes, meaning you don't have to tap the pump wire. Most who have the xzt+ claim it has a much smoother power band and as much or more bottom end power than a smarty programmer. And the timing only setting on it is the same as their MileageMax (I think thats the name) module.

 

The old XZT is a mild wire tap fueling box I think. Get the XZT+---it's a much better box and you don't have to mess with tapping the injector pump.

 

Cough adrenaline cough. If you're looking at buying an XZT+ AND the recon gauges, thats gotta put you up between 5-600, right?

Why not just spend the 675 and get the baddest thing running?

 

449 off ebay ebay with the xzt+ and recon gauges.

 

So 200 bucks for an extra 100 horsepower. That's cheap power right there...

 

Thanks all of you for chiming in. The majority recommends the XZT+ so there I go!

 

Great choice!!!!
