Ohh ok.  280 is a very high figure for a K03 TFSI engine. Youd need a upgraded HPFP to get anywhere near that figure.

OK... well in that case it didnt make a true 280bhp then. The Dyno was generous.


Anyway... back to the misfire. Have you not spoken to the place who remapped it?

I wasnt doubting that the tuners dyno said 280.... I am simply trying to explain to you that unless you've got a HPFP, you wont be making 280bhp on a dyno that reads correctly. In reality its probably making nearer 270.

Just to play devil's advocate @rich83...

My car made 270 with just a full BCS (sport cat) and Pipercross panel down at Hinckley.

Could it have made 10bhp more at peak with a well-flowing intake like a Ramair? Probably. I honestly doubt my Pipercross panel gave much more than a stock filter would.

There's also something worth considering with Seanie's map. If boost is tempered a bit at mid revs, say around 3k, it gives the turbo (mapper) a chance of producing a little more boost at higher revs. Mine made 345lb/ft of torque at 3200rpm, but dropped off a cliff soon after. This map makes considerably less torque at around 3k, but then holds on to the torque much better than mine.

So, it's maybe fairer to say that this car could indeed be making enough torque at high enough revs to make 280bhp peak power, at the expense of that good old k03 punch at low-mid revs.

It's also just as likely that this dyno, or any dyno for that matter, isn't entirely accurate

This is my graph. Where Seanie is making peak power - 5800rpm - he's at about 260lb/ft.

At 5800rpm my car produced something like 240lb/ft. A fair chunk less than Seanie's.

Because it isn't the tuner's responsibility to check or fix ignition/fuelling hardware.

@AJP That's was my opinion aswell, he has done his job and has been great with giving advice and help on what to do.

So thanks guys for your advice and I am going to go the route of changing coils first and then I will let ye know how things are going.
Appreciate your help

Thanks for the update!
