Boost controllers - Hybrid or Apexi
Help 
I put my car on the rollers at PE and it only managed 1.3 bar, on the road it peaks to a little over 1.5 and holds 1.5 to 6200rpm. It was mentioned that the link wasn't great at controlling the boost and I should think of a boost controller hence the Q.....
Graph
The spec of the car is
Link ecu
FMIC
EJ22t block
550cc injectors
SX fuel reg
TD05 FE
Lateral exhaust headers
Full decat HKS exhaust

I have an HKS EVC v and it will hold full boost to redline, they are readily available and easy to fit and setup 
Mine pulled 312 at PE on std uk map, HKS decat, VF28 turbo and HKS boost controller (MY98) running 1.2 bar boost on a hot day, remap?? who needs that
check out how flat the HKS EVC kept the torque line

ive got ahybrid one brand new but i think its only for 01- cars, otherwise you could have had that!
wouldnt have thought it was that bad at holding boost though? (the link that is)

Dont forget that you pulled some fantasic torque there so I really wouldn't worry if I were you....... mine pulled 286 and yours was 327 which for that same bhp is pretty impressive on your behalf

The fact that your car did not pull the same boost on the rollers as it does on the road does not mean you need a boost controller.
The heavier the load on the engine and hence turbo the more able you are to develop full boost. If you did not develop full boost on the rollers this indicates your car was not loaded up in an equivalent manner to the load developed on the road.
If your boost control on the road is adequate, and in my experience the Link can manage this satisfactorily, you are wasting money adding a boost controller unless you want more from it eg. to achieve big power figures on rollers and so on but you will probably have to make adjustments to the boost controller at the time of any rolling road run to achieve targets.

Here's the video clip
Chris called the other guy over as he thought it might have been spinning up, but there wasn't enough time to adjust it. I stopped filming as I thought there was a problem.

Thanks for the replies...
Would it be worth fitting the 18g to cope with the air flow at the higher RPM?
