Today on a private road I noticed that around 100mph with WOT the engine gets very hesitant...kind of pulsing power on a off but not really going much faster. It made me wonder whether this is the turbo just not being strong enough for the amount of boost I have it set to run on. I have the Squadra chip and a manual boost controller which I think it set to around 1.3 bar, although I do get some bleed off (can't find a leak, might be the IC)
I think it is either the turbo not being able to cope any more although it still does pull very hard and quickly from 3-5000 rpm. Or it may be some ignition problem that only comes about when under high load. I have the NGK B8EGV spark plugs fitted.
Any thoughts on this?
Thanks,
Jack
