2.6 pulley from lethal performance

I got me a 2.6 pulley from lethal performance. Is there a tune in the trinity I can use or do I need anything special??? I only found a tune for 2.7 pulleys on my tool. We want to install the pulley this weekend.

Please help

Yes, the pulley tune will work fine.

I have installed a smaller pulley and your tune. Boost is great, but the exhaust lost its popping some when downshifting. Now the Shelby sounds very poor. How can I get the great sound back???
Next question: Is there a speed/rev limit in this tune or can I change these by modifying the tune.

speed limit is not present on GT500 to my knowledge, rev limit is there ofr a reason, but you can raise it if you like.

To get some popping under decel, there are DFCO settings that can be played with, but they generally cause a loss of fuel economy.

Mikel,

there is a speed limit of appr. 155 mph. With the custom tune I could kill that limit. For revs I like a limit for engine safety reasons. For the popping sound under decel what could I try exactly without causing problems to the engine? Fuel economy does not matter on a nice car like this one. 10 or 12 mpg, who cares?
