Stalling after a bump

[cynider]

My car almost stalls after I hit a bump. Does anyone know whats up with that?

Mods are: FMIC, 12psi, intake, full exhaust, standard timing. I always use Optimax and octane boost depending on age of petrol.

Any help appreciated.

I assume you mean when you're going slow like over a speed bump? Usually that's to do with an aftermarket blow-off valve, an air flow converter like Apexi's S-AFC can fix this.

Could also be something wrong with your ignition wiring and bumps are jostling it loose somewhere momentarily.
