Hi there when i brought my 850R manual it needed a new engine, we managed to get hold of a V70R one. Since then i have had a new intercooler and 18t turbo fitted by volvo through the other guys insurance after a i hit a spare wheel in the middle of the road. I have had the car remapped since then but had an air leak on one of the intercooler pipes so never ran full boost, i had this fixed today. Since getting this done the car picks up alot better and seems to have full power but when on full boost it runs lumpy like its misfireing and not getting enough fuel. Could this be to the injectors not being big enough and if so what injectors should i get. It is running orange ones at the moment but have got white ones as these were in my old engine but not fitted for some reason. thanks
