I haven't tried it but have been always told to stay away from "chips". Also looking at their site they're claiming their most expensive one (over $500) will give you 230 hp and 255 ft-lbs on just a tune, i find that hard to believe. The ft-lbs number isn't too far off reality but i'm currently running a COBB stage 3 with supporting mods and am only doing around 220hp at the wheels, perhaps they're listing flywheel numbers?
