UAE Boost Club

Hi everyone my dad recently purchased a bmw x5 twin turbo and i was wondering whats the best way to get more boost . Should i simply by and install a boost controller or should i go get a remap from a garage? If so which garage would be best and what are the prices like?

of course go for remap,increasing the boost without letting the ecu for the new target boost it might let it go into limp mode...i would have helped and remapped it for you but i am not in UAE now.

Thanks.

Scary how you say "simply buy and install a boost controller"

An electronic boost controller is a good start if you are thinking of messing around with the boost. Install it and do some adjustments to the settings etc. As you don't need in theory to have a remap if you just up the boost pressure a little bit as this is what a Electronic boost controller is designed for (Piggy backs the ECU, so tells the ECU to make adjustments to timing etc)
BUT (IN BIG LETTERS) if i was you and with that type of car ... i'd take it to a garage that knows about this sort of thing.
Munich Motors in Al quoz have BMW tuning parts and ECU equipment. Could be a good starting point.

My experience is with a Nissan S14 and Mazda RX7 , installing and set it up from help notes and online guidelines from known specialist in UK.
