I have had my billet DTT tranny for one week and 4" exhaust for 2. I have not yet verified exactly, but I am seeing a huge difference in MPGs. I am guessing 3 plus. Anyway, just thrilled. I hope the Mach 1.6 will get another mile. I will be around 21mpg, if so, maybe 14-15 pulling trailer. Nothing like enviromentally correct power, almost seems like a paradox.

 

Heck yea I love my DTT. Saw a big diff in everything when i got mine. Once you get those mach sticks and super B, you'll be ready to kill it!

 

I look forward to killing my 4500.00 tranny. Hopefully staying under 400hp will give it a long life. I already took the bug vacination.

 

I've had the DTT tranny (Torque converter, valve body, clutches, etc.) in my 96 since 2001 at 86K miles. It's a solid setup.
