BM3 Stage 2 E30 and Catless

Hey everyone,

Is anyone out there using BM3 Stage 2 E30 OTS on their N63TU(2, 3) on catless? I ask because I've been running Map 1 E30 on an otherwise stock car (plugs, coils upgraded only) and I'm seeing the benefit of cattless, but I also see that PTF suggests High Flow DPs for Map 2 E30.

I saw a thread a while back indicating performance differences on maps were negligible for catless vs. High Flow for OTS tunes but was curious if going DeCat vs HF on Map 2 causes any issues.

*EDIT

Got clarification from Halim over at PTF who verified catless is fine for stage 2, high flow was just a recommendation due to having been the primary hardware they tuned for.

I’ve been running the bm3 stage 1 E30 tune and ran 11.6@123mph and just recently installed my downpipes and the stage 2 tune and will be hitting the track on opening day to test the performance gains between the stage 1 and stage 2
