How to prevent meth spraying on 2-step?

I think you will have to do a lot of tuning just to get the AFR where it needs to be while it's spraying for max performance. For most people on this website I think it doesn't really matter because cutting 1.2x and 1.1x 60' are only things that crazies like me are actually shooting for attaining, but I still think for maximum performance that keeping it off while on the trans brake is best.

I don't know for sure. I use to do it on my old turbo car and my AFR with my two step turned off was in the high 10's spraying meth on the trans brake. I can only imagine that with a leaner AFR it would come out of the hole harder and then progressively richen the AFR up as boost comes in and wheel speed goes up once the car is moving.
I would think that being able to progressively bring fuel in instead of having to take fuel out or do other things to compensate for the methanol spraying would be easier and faster along with being more responsive.
I'm going to try it both ways when my car is up and running with the turbo set-up if I ever remember to try it out both ways.

I got my 2-step today and wired it without a meth cut off. Sounds sick but car stumbles when I let off the gas. I haven't tried staying in it yet. Seems I should just wire a cut off for the meth since it has no benefit being sprayed on the two step for me.

the turbo still makes heat while your on the 2 step, spraying meth while on the limiter definately has merrit, but if the car loads up as Martin suggest, then you need to pick your poison

Had this problem, but I just turn up the boost that the meth come on so I can build more boost with out it spraying. Had mine coming on at 4psi but car would flood if I try to leave with 5psi, so I set the meth to come on a 9psi, and I can leave with boost to that number.
Hey- Thanks for your reply about the boost with a 2 step and a 6 speed running a procharger. I don't want to sound stupid here but I thought the car needed a load to build boost? WHen I build RPM to get ready to launch (I haven't bought a 2 step yet), the boost gauge shows that I go from vacuum state to maybe 1 lb of boost (if I remember correctly). Now, that is without a 2 step but I would think the 2 step makes no difference as I'm holding the RPM with the accelerator and the 2 step is doing it by cutting spark...I've been searching posts but haven't seen where I see people building boost on 6 speed procharger with a 2 step, only on turbos. Did I miss something
