I know I should have logged my runs, but didn't. I was really going just to have some fun and teach the wife how to race (it was her first time out ). The weather was actually better last night, high 80's last time and mid 60's last night.

I have a Helix Front mount, charge pipe and a Cobb sitting in the garage. I planned on running the BMS flash combined with the JB4 and then adding meth. I just thought it would have been good for a mid to low 13 after seeing what it did stock. However it wasn't. I think the Cobb may help a bit more at altitude. I'll have to log a few runs and plan on running some 104 next time I go up to see.

Of all the things I love about Colorado, the altitude for performance certainly isn't one of them...

What does it take to knock down a mid 12 up here? Anyone doing it on stock turbos?
