There are quite a few dynos here. Autoplus (EDSA Greenhills, near Barrio Fiesta and Kamayan) has one, but tuning time is expensive. Best advice? Get everything else worked out first, then buy an E-Manage or an SMT6 programmable, then get it done there after you're sure your setup is okay.

There's a slightly cheaper one in the south, at Creativespeed near BF Resort, Alabang-Zapote road, but I'm not sure how accurate ( ) their dyno is.
