Hi just joined and not had the car long but noticed its bit hesitant pulling up through the revs. From about 1800 revs upto say 4000rpm ish then once the pedal is right down it clears and goes like a train. It looks like someone may of had a dump valve on (just guessing) as the front right corner on the engine cover there was a pipe cut and had a T piece between it but nothing on the end of the t so was hissing air out, so replaced it with a straight pipe. Would you say that sounds correct ? The car is standard, any help appreciated thanks. :thumbsup:
