has anyone sorted the mapping out on the above? I have read a fe times about this flat spot and now the car is getting more and more sorted this hicup at 2K is REALLY annoying!

thoughts please?

Hi Doug,

I know chip #10 very well (I' m the author ;o) and from my experience it is not normal that #10 produces a hickup at 2k rpm.

The stock codes tend to produce a flat spot around 3k, that's a well known issue ... but its not a hickup ... its just a flat spot.

I'm sure that the roots for your hickup are not chip #10.

What could produce this hickup ???

- is your wastegate capsule adjusted correctly to 0.65 bar base setting

- are your sensors giving corect readings ? (check with freescan)

- how about your alternator ... is there an erratic volts reading around 2k rpm ?
