Alright guys! New here to this forum. Calling all Golf R gurus out there!
Quick intro, bought a 2012 Golf R exactly a year ago. Thing came with a APR stage 2+ tune, IE HPFP internals, IE air intake, poly motor mounts and solid dog bone mount, BC Racing BR-series extreme drop coil overs, Godspeed rear adjustable camber arms. As soon as I got it I had a master VV tech at work do the timing belt/water pump, Haldex service, all maintenance that was needed for 55k miles on it. A few months ago my Golf R broke down on me, noticed a bit of ticking coming from the engine bay, drove it in to work( Luckily I was 10 miles down the road). Once I got it to the shop I opened up the camshaft chain housing to inspect the chain and tensioner, once I removed all the components I found the infamous HPFP bucket worn all the way down and the stem from the pump worn into the intake camshaft. Got the new IE internals ordered, new camshaft, chain and tensioner ( no big deal). Took roughly about a month and a half to get the internals due to an issue when ordering in the meanwhile installed everything else and a few extra goodies ( CTS billet valve cover w/ catch can set up, Fuel to air gauge, balance shaft delete kit from VIS). Once the internals were finally installed and everything was back together and engine was running that's when all the problems began. Other than the obvious vibration from the balance shaft delete, I started experiencing a bog or what I can describe as a fuel cut off right between 4-5k at WOT. Car would not go after that and I would get a noise as if something was clogging air flow ( it wasn't my R anymore :'( ) . Started with the basics, checking for faults... none present at the time, called the guys from APR soon after that. The guys at APR told me that maybe since the car was down with the battery disconnected it might off lost the tune so luckily my buddy who own the car before me had the program switching feature on there and was able to get it back to the stage 2+. The car felt a great at low rpms but again car would fall on his face between 4k-5k, to make this long story a little short I have done throttle body cleaning and alignment, set basic settings on the stock manifold flap motor, bought a new HPFP, cleaned out IE air filter, re gapped the new BKR8 spark plugs, upgraded coils to apr gray top coils.. nothing seem to do the trick. Moved on to checking fuel pressure, coming from the tank the original reading with our fuel pressure tester at work the readings were 3.2 bar to 3.6 bar with load, replaced fuel filter, fuel pump and swapped over the module from my shop foreman's MK6 R to mine and also swapped tunes from APR to IE stage 2 pro. For the first couple of days the R felt great... BUT.... it was somehow over boosting, the PODI boost gauge RED lined at almost 30psi a couple of times where it would usually boost between 24-26 psi before the failure. I was obviously super careful driving the vehicle like this because I didn't want to blow up and engine on another of my cars. So here I am a few thousand dollars later and me and the guys at work are stumped, re checked timing and faults are not there. Any help or suggestions would be greatly appreciate it....
