Ran almost a full tank through yesterday evening and it's doing well so far, does have a tiny bit of decal pop around 2k-2500. I have not adjusted for development pop yet and I will play with throttle progressivity. I'm going to run 1 more tank through before I change any settings or start an autotune session on it.

With your catless headers you may want to give the dresser dual maps a look.

Or will it just alter the decel enleanment table? I know, I'm getting techie here...

One thing that I definitely like about the FP3 vs other options is that it USES the O2 sensors - it doesn't ignore them or have you remove them. A closed-loop tuner like this HAS to be more effective than an open loop one.
