Questions before purchasing the Gryphon

Thanks for the info. I understand that.

Is it possible to get an economy tune? Or is that what the tow tune is for?

Because I do not see that as an option.

It is certainly possible to get an "economy" tune. It's what I have loaded into my Level 1 position. In general, it's just a non-towing performance tune with somewhat altered part throttle shift points and MAYBE a slightly changed "fuel map".

All you have to do is say that you want an "economy tune" in the remarks section of the order form and Bill will write it that way.

The tow tune is designed for pulling loads greater than 2500#. It is different than an economy non-towing tune.

Alright.
I guess I had more questions than I thought.
What do I put down for my exhaust diameter?
I have Borla split rear
it comes into the muffler at 3
and when it splits into 2, it goes to 2.25

I am not any kind of authority on exhausts. I suspect the 3" figure would be the correct value though, because it's a "choke point" (the narrowest part in the new exhaust). You're not going to get anything through the 2-2.25" pipes that doesn't go through the single 3" section first.

88Racing is more knowledgeable about exhausts though. He might notice this thread and chime in.

If you have maintained the original stock "Y". This is the pipe that comes off the headers with the cats and o2 sensors and then merges together to the point where you'd put a cat back on.
If this is the case then just put down Borla cat back system 3" SI/2.25" DO.
But..........
If you split the "Y" and put truduals under the truck then Bill needs to know this.
Hope that helps.

Peace

Thanks 88 =)

Eh, sorry, but yet another question.
Does it come with 3 stock tunes? And when I get my custom tunes, will I still have access to the 3 stock + 2 customs. Or is it limited?

So I would have for my case;
stock tranny
stock 87-tow
stock 93-per
custom 87-per
custom 87 eco

Is this correct?
