Help! MY99 unmodded Turbo.

Just spent over £700 on a 60k service, including cambelt change and two new front discs. Main dealer thought that this would cure my flat spot, but mentioned possibly having to replace the MAF sensor if the problem is still there.

Drove home last night to find that it is. I can accelerate through it (delivery of power is only slightly hesitant between 4 and 4.5k revs), but you don't spend this money on a performance car of this kind, and expect a flat spot of any sort!!

Any ideas on likely cost of replacing the MAF?

I'm NOT happy...I may soon be an ex-scoob owner at this rate.

Thanks to one and all.
