Boxsters are no match, even the carrera struggles until the twisty bits!

Keep on it you'll get there, maybe find another specialist, the dealers can be very expensive, and that's before they start adding parts to the bill.

 

No match is a bit harsh, 13.4 1/4 mile 228 bhp per tonne, the boxster s is no slow car, a standard xjr has around the same specs, beating one by a few car lengths is a good victory in my book.

 

Sean's car Ran an 11.9, so 13.4 is wayyyyyy slower

 

My car has just been in a second time to have it's fuel trims looked at along with a second issue of hesiatation under load - which now seems to have gone away.

They spent a second 5 hour session investigating the fuel trims running high on both banks. The only thing they can advise it to be is my 200 cell sports cats. I never knew this could have this kind of effect due to having less restriction in the exhaust, can any-one confirm?

They have now gone over the car with a fine tooth comb and cannot find any air leaks or anything else related to fuel trims being high.
