Hydra ECU mapping changed? Help!
Hi,
We have a 2006 Spec C which has a decatted replacement exhaust and Hydra ECU remapped by Richard Bulmer.
Now we have always been amazed at the power of the thing, it has been totally manic. I was told a conservative estimate is 360bhp, and have seen others advertised at 380, which I could well believe.
It would pull crazily with turbo shrieking from just over 2000rpm....until yesterday.
My wife told me that going down a slip road it just cut out, no power at all as if it had stalled, but then came back a second later.
Since then it has run ok, but it feels like it has lost 50 bhp, the turbo is cutting in later, below 3000rpm it feels a bit dead, and shriek sounds a bit muted.
Any ideas? I was wondering if we have a bad tank of Tesco 99. Has the ECU switched to a different map, will it adjust itself back automatically, or will it need reprogramming?
I thought it felt a little better at the end of the day, but perhaps this was wishful thinking.
Is this a common thing?

Unfortunately it was done oop north. So I can't take it back to them, but I'll give them a call.
Really what I was wondering is whether this sort of thing happens generally if you get a bad batch of fuel.

The Select Monitor will be about as much use as breasts on a fish with the Hydra! 
Mark,
This could be anything mate..... take some guided advice and get someone that knows what they are doing to look at it. As a first point of call I would speak to Richard at Tracktive. I certainly wouldnt be driving it hard if the engine had performed that drastically different, until it had been checked out.
