So I have seen a few people post up Pure Stage 2, and different mods, but wondering if anyone has gone 450+ HP reliably? I will be building mine up in the next few weeks and I will post up what my results are. To start with, I have an ER Chargepipe, ER Catless Downpipe, BMS Intake, Wagner FMIC. I run and approx. E30 blend. On a Mustang dyno, JB1 on Map 1, I am 336 HP. In the order process, I will be adding a Pure Stage 2 Turbo, Fuel it PI plate, Fuel-it Stage 2 LPFP, and considering a small addition of Meth to assist cooling (I am in AZ, and summer ambient will be 100+ every day). Who else has a seriously modded F10/N55 car? What have they achieved?
