I have a 2007 Golf GTi - BWA engine
So the only mods i have done to it are NGK-R Audi S3 plugs, a Ramair induction kit and a non resonated turbo back with a 200 cell Cat Milltek exhaust
Last monday i got a remap done by a well know tuner,
So the car started at 195 bhp at the flywheel and finished up at a whopping 280.2 bhp,
I am delighted with these figures ........ BUT why am i not enjoying it and here is why,
When I am driving it, I am in 4th 5th or 6th gear at 3000+ rpm and i have a misfire or a sound that is coming from the engine that sounds like the fuel is spitting into the cylinders, its very annoying and i am not getting the potential from this great car as if i give it the boot it struggles to get grip up to 3rd gear (I understand that as the torque is 300fp) but i have no top end speeds with the misfire as i dont want to do damage to a graet healthy engine.
I am wondering has anyone else had this problem and what could i do to rectify this problem??????
All help greatly appreciated
Thanks Seanie

More than likely if they've never been changed. First time I hit boost after map was applied, I had the same symptoms. You need diagnostic kit like VCDS to measure misfires to know for sure
Sorry to jump on your post can you tell me how to check for misfires with vcds please I have full genuine copy and I suspect I have a misfire :(

No you don't I have a standard hpfp

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?

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

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

Why not just hand the car back to the tuner and say fix it? :thinking: :doh:Because it isn't the tuner's responsibility to check or fix ignition/fuelling hardware.

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

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.

Dyno lottery.

Well guys just to update ye I have just put in the genuine red coils from Audi and what a difference they have made and I want to thanks all of ye for your advice and it was a top notch diagnosis
Thanks for the update!
It's all too often that threads just fizzle out after the problem is solved and no one becomes any the wiser from reading them.
Another win for the forum members :star:

I've just ordered some of those from AKS. I don't have a misfire problem but mine still has the original black coils, so could probably do with a refresh. Good that they fixed your issue!

I had all of mine changed for free at VW as part of a recall. Ring your nearest dealer and ask them about it - it should still apply.

So, what's the prices of these coil packs?
Ta.
Less than 100 quid from aks tuning

Yep, 1p less, inc delivery.
The coils are £40 each from Audi.
