Opinions please. I'm thinking of stacking the TST CR75 module with the C3.1.
I've had the VA about 9 months. It really works well on the low end up to 2200 RPM. I pull a 10,500 lb camper and am looking for better top end to go along with the low end.
Ordered a Performer fuel system from Shane to feed the animal.
What's your thoughts?

 

I don't think it's gonna work since both alter the timing. I tried a TST/Quadzilla stack and my truck rattled really bad even at idle. That Rokktech is gonna have to be turned back to stock or removed if you put the TST on there too. The TST really adds a bunch of timing...

 

i have been running the VA 3.1 for a few months now along with my smarty and it seems to work pretty well. at times i do get a little timing rattle but if i throttle up a little more it goes away. i also have the tone ring mod done. i have been thinking about turning it back to the stock position to see if that helps any.
