I will be upgrading to a fabspeed header (no cats) + tubi catback + revo tecknic stage 2 remap + EVOM + de-snork in next 10 days. I will of course share my results with you. I considered GIAC but it sounded like a waste of money based on the reward v outlay. Revo are looking at around 25bhp for the remap alone. Theoretically I hope to be +50 bhp on OEM. Will keep you posted...
