This is a really weird problem that I can't decide if its a surging issue or something else but it makes the car undrivable.
If I give it more than 50% throttle the car accelerates fine and boosts as normal. Which is fine when you want to go faster.
However on a long trip yesterday I found that anything less that 50% or you know when you need to keep at a steady speed, which requires a fine amount of pressure on the throttle, that the car boosts to around 5/6psi then goes to 0psi as if you have lifted off the throttle (but not a vacuum) and then builds again to 5/6psi then drops to 0psi and will continuously do this eventually leading to a jerking motion and you have to come off the throttle.
Any ideas?
Recent updates are a FMIC, New N75 and new MAP sensor and running a stage 1 CC map. (Getting it mapped end of January)
Car is horrible to drive atm
