Doing some research and reading up on 2 steps in general, I came across some posts which regarded that in the long run using a 2 step launch control while having a high flow cat could be bad for the cat.

The post was in the Dynoflash 2 step sticky and I didn't see any response to it but it made me wonder because I recently had the 2 step flashed in and I'm running a hfc w/my TBE.

Since the post was very vague, I was wondering if anyone knew any specifics about this theory and why/how it could be bad??

Any help would be greatly appreciated,
Benjy

 

You dump tons of fuel when you use the 2 step, if you're going to use it with the hfc just hit it once or twice and launch...instead of some people like to sit on it for 10-15 seconds before actually launching.
