Is there any way I could tell if my car has had an induction kit fitted in the past? The reason I ask is because of my ongoing random CEL light issue at high boost. I noticed the other day that the black hose (with the MAF) from the airbox to the intake hose was loose. I refitted it properly and now the car feels strangled and seems to have a flat spot between 5500 and 6500rpm. The intake hose after the airbox & MAF is a blue Samco jobbie and it seems strange that you'd change that, but leave the standard airbox in?
I have a Hayward & Scott cat-back exhaust and I'm wondering whether the car was mapped for this and an induction kit, that the previous owner maybe removed before selling it.
I'm still getting a noticeable lurching/hesitancy on boost at full throttle in high gears, only now I seem to have restricted the airflow by fixing the leaking joint it actually feels slower!
I suppose the best bet is to go and get it rolling-roaded somewhere and see what's occuring, it's just frustrating not knowing what's going on!
