In case people are wondering, here is how they perform on standard "pump" gas (no meth, no E85)
both were e-tuned by atvfreek (who's tuning me) and both live in same area (thread here: BNR S3 and GTX3071 comparison - Mazdaspeed Forums)
but, here is the dyno graph for those whom are interested:
mod list for BNR:
Catted full exhaust
FMIC
Cobb SRI + TIH
HPFP internals
GTX3071:
3.25" MAF + BT inlet
HPFP
DNP manifold
catless DP
FMIC
ported intake manifold
anyways, just thought i would throw this out there as a FYI to people looking at/for options
the biggest limiting factor on both cars is that normal petrol just isnt knock resistant enough to allow them to push more power (also the injectors down allow more than about 400whp)
