Misfire 4th 5th 6th after remap
« on: January 28, 2017, 11:02:17 pm »
Hi Guys

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

Standards are fine, R8's if you like red. Both do the same job

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

Sound job well I have a full service history and there is no history of changing coils and you hardly know the original part number for the R8 coils

Theres no way it made 280bhp... thats a very optimistic figure.
