Fitted this on the car the other day runs perfect. Quick question though just to make sure its done right.
Ive got a 3 port, blanked off the top and middle with a bolt. The bottom hose is still fitted into the Apexi housing. Does this need blanked off or is it ok the way it is. Also drilled out the hole to 1.5mm. Ive set the boost to 1.0 bar in 5th gear



On the plus side, its a cheap way to get more boost and torque. Major grin value, but the fuel takes a bit of a hammering

Cheers Slippy

Fine. What difference does it make drilling the hole bigger, does it spike like that?

If you have a 0.5mm bleed, you can often develop full boost with very light throttle. This has two consequences, one is that it makes part throttle control of your car difficult, especially when cornering, and two there is a risk that your engine may run lean in this situation due to the base fuelling map not expecting to come across a high boost/small throttle opening environment. Spool-up may suffer slightly but drive-ability and safety is improved.
