I just got my BRZ (AT) tuned by Bob at @
Drift-Office and I am very pleased with the results. JDL EL header (catted), Nameless catted/resonated downpipe (2.5"), A'PEXi catback, K&N drop-in filter.
3rd gear pulls, 92 octane:
Run 1: Stock header, Nameless downpipe, ISIS catback, K&N filter
Run 3 (pre-tune): JDL EL header, Nameless downpipe, A'PEXi catback, K&N filter
Run 9 (post-tune): JDL EL header, Nameless downpipe, A'PEXi catback, K&N filter
Torque dip?
Thanks Bob & Bill!
