Suddenly feels like no boost and using a bit more fuel with a little more soot, only mod is blanking plate otherwise stock. Tell me it’s just my maf as I usually go limp mode every month before it needs a clean but haven’t had limp mode for nearly 3 months since maf and fuel filter clean out.
Also noticed while driving under load (as it hardly did it in 4wL) sounded like a vacuum cleaner under my bonnet. Thx in advance
