I am not sure. Was just browsing through the APR website(on the date that I've posted my last comment) and found out they've released the Stage 2 Map.
I had the APR stage 2 Map installed in August this year along with a turbo back Milltek exhaust. I had the turbo replaced at the same time due to shaft play after ~120,000km.
Prior to the upgrade the car was running a 2011 CAVD block (stock pistons) with a 2012 HPFP, S3 intercooler, K&N airbox/filter, DV+ diverter valve, odyssey PC680 battery and various other valve and small part replacements. It had been on the APR stage 1 map since 2014.
The Map went well initially and was a nice bump up from the stage 1. The torque curve felt much flatter and the rush was pushed up the rev range to be more turbo focused. The exhaust sound is good fun too with some pops and crackle that you don't normally get in the 6sp manual
Boost Limp
Since then I have experienced the boost limp on and off. Worth mentioning that one of the hoses from the intercooler has pretty much popped off the lower boost pipe elbow (engine side of the intercooler). Healthy peak boost for the stage 2 map on my PODI gauge was showing about 22PSI. Now it's around 18PSI, when the limp kicks in and it's limited to 15PSI.
Alternative Stage 2 Options
As far as alternative stage 2 options go here, there's REVO, Harding Performance (ex-distributor for APR in Australia) and e-tuners. I've noted Blower's comments on the AFR issue and potential knock sensor sensitivity.
I'm not in a huge rush for a new tune as it'd be an expensive exercise but would like to lose the boost limp.
Couple of questions:
Is the TMG coil spacer essential for the R8 coils?
Is there an alternative? (the TMG postage to Australia is like 100 Euro)
Would the G revision stock coils be sufficient in the absence of the R8s in your opinions?
Would you wrap your downpipe?
