KO4 Upgrade Question

[rweir]

I hear you ... but my problem is that is going to be a big issue to get it back to the people that upgraded it for, it is my problem because of the distance.

I spend 5 hours the other day playing with the car, but never got to those speed that made it an issue ... so feel it would be a wasted trip to 'try' and resolve it ..

Why don't you take it to a reputable UK tuner just so they can run the ruler over it to make sure that it isn't sticking DV's, perforated TBB or faulty MAF. While the problem does not seem to manifest itself above 140 that's not to say that harm isn't being done at slower speeds.

I ignored a faulty MAF at my ultimate expense.

I think I may have found the problem [img]images/graemlins/rocker.gif[/img], but need a better day to test it ... Think it was the N75 valve, just changed it and feels a lot better ...
