I have the 93 race on my manual, and it's fine even in stop and go traffic. lately when I reflash, if I get on it too soon after reflashing, it goes into limp mode until I reflash again...then no problems...weird!

 

I live near and work at the biggest Inland Oil Refinery in the U.S ( ConocoPhillips....Borger Plant).....and we cant get 93 Octane.....Unless you buy it from the Track .....so I settled for a 91 Octane Race Tune....but I have not figured out all of the stuff I need to d/l so I can install it on my SCT 2....but when I do ....I hope that it will help my Cars Performance out some....that and the fact that I am Sh&T Canning the O/R X-Pipe too and going back with the Stock Catted H-Pipe again to see if it will help me get the bottom end performance back that I lost

 

Dude i am running CMCV delete plates, JLT intake, Coffin catbacks, and offroad-H pipe and used to run dougs tune. Loved it for a while but then i tried Tillmans tune and the car REALLY woke up even more. Both tunes were good but it just seems CR had more time to tune the car even further.
