I'll be ready to purchase a custom tune at the end of July and just wondering would a dual tune be worth it? I've seen where nelson and wheatley has a 89/93 tune or just a 93 tune, but from what i've read the 93 tune is for racing and cannot be used for towing and i wanna be able to tow if or when nesscary so any advise would be great and one more thing i still havent decided about Nelson or Wheatly so any help there would be great too!

 

There's not really such thing as a "dual" tune.

There are 2 spark tables 1 for a high octane and 1 for a low octane that allow your engine to jump down the the low octane table when it senses knock. You can tune the upper table for 93 and the lower for 89.

You can also tune for transmission stuff and use the tow haul button for "performance" the tow haul button will only change transmission characteristics on the fly such as torque management shift points ,etc. So essentially you can have both but it's no really a "dual" tune.

 

Damn Mark.. you almost sound like you know what your talking about... JFWY

I agree btw!
