Rb20det Power Cuts In And Out!

[NizmoNigga]

Hey,

My mates rb20 keeps cutting in and out of power. It only happens when he keeps the accelerator in one position to maintain the assigned speed limit. When it does cut out its only for a second then the power cuts back in and few seconds later it will do it again but then it might do it few minutes later so it is not a constant cut out, just now and then when it feels like it and only when the accelerator is in one position.

Also boost controller/tap being a manual one seems to change its boost settings which we cant figure out why. This boost controller you have to loosen the top nut then set the boost then tighten the nut, which we tighten very firmly. Boost it set at 1 bar or 14.7 psi but then some days the boost gauge would read over 1.3 bar.

We have no idea if the second problem is related to the first one if so i don't see how it does. The first problem is our main concern right now.

Any ideas?

Thanks
