The car is fitted with a 2871r with ported wastgate.
Forge actuator with the strongest spring available
Actuator rod was set to nearly a whole hole over waste gate arm.
On the dyno it holds 1.65 bar upto 4,800 rpm then drops off to 1.4bar
I've tried adjusting the boost controller but it still tails of to 1.4ish bar
What are people's thoughts? I've heard of people having problems with these boost controllers not holding boost high up but perhaps the problem lies else where.
