Hi All

Well I have had my HGT for six months almost and we have put 5500 Kms on it. Cracking car and I really enjoy driving it.

However it does have a flatspot in first gear between 4000 Rpm and 5000 rpm. Under strong accelaration it pulls like a train to 4 grand then goes of the boil to 5 grand and then goes like a train after that. Cannot replicate it in another gear (i.e 2nd).

Anyone else experience this. Should I be concerned or just change up early?
 
I suppose it's possible it's engine management, perhaps to do with emissions? That's a total guess btw :)
