You should be fine with 8.5:1. My awd talon was a 8.5:1 comp from the factory and never had a issues with driving out of boost. Yes I know it was a 2L but it also had hella more weight to deal with. Also the stock 1gen DSM run a 7.8:1 ratio

You should be fine with you 8.5:1. Now you spot a small difference if you jump from your car into a 9:1 ratio car but not by much.

If you really worried about it, just run shit ton more timing out boost in the lower RPM, like what us still NA people have to run.

The gt2560 sounds more appealing every step of the way...especially with the 40lb/ft gain at 3500rpm according to the FM dyno.

whens the last time you shifted and the tach was at 3500RPM while running thoughout the gears?

by all means I like a little quick turbo, however, the torque drop after it's spooled is a BIG compromise....
