I’m going to add to this.. a couple of weeks ago I had turbo failure.
Peddle to the metal as soon as I let my foot of the accelerator BANG. 19 plate 34k on the clock. Revo map installed last year. The van has always had a whistle with the turbo but the map made the whistle more prominent (cool sounding
). After a year it finally gave up. I did notice over the last month a flat spot at around 2k revs and it felt sluggish.
Was the map to blame? Was it a weak turbo and the map accelerated the failure and it go later on without a map? Who knows. I’ve heard all the comments “just buy the faster one” blah blah
All fixed and running like a dream now. Thanks for all your help.. you know who you are
