The car has has had a stage one custom code map for over a year now and has been perfect, last wednesday installed a forge fmic and everything was going fine until today driving home. When the car is under load it has developed a major stammer when entering boost as if hitting a wall but when in boosting when the engine isnt under load everything is well and it pulls fine, i put it down to a boost hose blowing off but under closer inspection all were intact. Got the car linked up to vagcam and there are no faults at all.
Is this something to do with my map, does it need stage two now that i have a full miltek and forge fmic? To me this is the logical explanation, but why has this occurred 10 days after installing my intercooler when everything was perfect before hand? had the car out last night for a good hour driving and nothing was wrong!
The car's in for stage 2 on monday to hopefully remediate the problem!
Anyone experienced this before?
