I have a UTEC and have refrained from trying the launch control feature because the Turbo XS instructions explicitly say not to do so if you have a converter on the car -- the issue being that you will send too much raw fuel into the cat and destroy it. Yet, it seems like there are a number of Dynoflashed cars around now using the 2-step with converters. Is Turbo XS just being over cautious in their advice? Thx.
