I will have a word with them, i had someone answer my thread on TFSI tuning Facebook group who also said its a software issue when max boost 2500mbar is requested, on stock MED 9.

It only throw that code at 130 kmh in 3rd...  :innocent:

Thanks, its going in for some track day mods tomorrow.

It can be modded that it doesnt go in limp and show 0299 without removing dtc. Its a Softwarething and needs to be done if max is requested ( med9 ecu - 2550mbar )

Car is much improved .

Had super pro ball joints fitted to give 1.8 degs neg camber

EBC orange stuff race pads.

Geo set up and brake fluid change.

New caliper on ns front as old one leaked! .

It goes round roundabouts like it's on rails.  Can't wait to try it on track.

Top work as ever from Paul & Liam Maxtreme Ltd

Getting fuel cuts at full throttle. No fault codes just stumbled in mid range pulls. Do I need a HPFP?

It’s quite possible, have a read of this thread - www.mk5golfgti.co.uk/forum/index.php?topic=14350.0

I have a stage one k03 car, which spools up earlier needing more fuel, and it felt stronger with the VIS pump despite no changes to mapping or fprv.

Is the boost still holding 1.5bar? Easier to see now you have the gauges.
Its normal to get spikes but if it holds 1.5 that's quite a lot. Its possible it cant fuel enough.
Are you sure its only got a stage 1 map on there? should a stage 1 request 1.5bar?

Yeah the MAP sensor only reads to 1.5 bar gauge (2.5 absolute) but it doesn't matter.  I've requested and run 1.7 bar boost (gauge) with no problems before. Have a chat with Vince at Stealth as he can explain it better than me. It's not a big deal.

What RPM is the fuel cut occurring?  Sure it's fuel cut and not the ECU combatting compressor surge? K04s exceed the engine's VE at approx 3000rpm if running greater than 1.4 bar and the ECU goes into 'what the f'ck is happening here mode', which feels like an abrupt stutter, and then the power resumes. 

Stock and Stage 1 don't hit that problem because they only request 0.9 bar and 1.2-1.3 bar respectively.  It's why I keep banging on and on like a stuck record......just don't do 2+ maps!  You can pull back the N75 duty around 3000 to get around it but it just feels like a nasty flat spot when you do that.

Dunno how you got -1.8 with the SP BJs, most I could get was -1.2  :grin:

You definitely need a HPFP if you're running 1.5 bar regardless!  I recommend the Integrated Engineering one as the piston shaft is the same diameter top to bottom, which is a lot stiffer and stronger than the usual method, but the VIS one isn't too bad for the price.

I like the boost gauge mate. Do you still get good airflow through the vent or is it more for show?

It still blows air but the direction vanes are no longer in there as had to be removed
