Hi Guys.I fitted an S 280 in May and have been chasing an overboost issue ... I'm in Africa and car is remote tuned by a company in the UK .. my car boosts 1.8/ 1.9 bar on a 1.45 bar map .. I've fitted a new boost control solenoid and we tested the supplied TT waste gate/ actuator which seems to be working as it should . I live Inland 5428 feet above sea level . I drove 400 km to the coast and the car was boosting exactly as it should with a 1.45 bar and 1.65 bar map .. as soon as I reached higher altitude the fiesta is overboosting again .. this time probably harder than previously ..
Any ideas please?
