does apr have graps for the apr stage2+ or does anybody have experiences with this tune
If you had a VW GTI , I would say don't hesitate, the max gains don't seem high but its a significant difference across the power and with lots more lower-midrange torque .
not sure how much better the stock fueling is in the TTS in comparison to the GTI, but I think it will help the turbo lag on your TTS.
A good way to confirm the max fueling is to go wide open throttle while your driver info screen is displaying instantaneous fuel economy.
In Canada we use metric units, but u could do the conversion.
I was pegging 52 Litres/ 100 km instant readings at WOT with the APR pump on my GTi .
my OEM pump was maxing out at 35-38 ltr/ 100 km
2007 GTi Black Magic, APR Stage 2+
2012 TTRS Sepang Blue on Titanium Blades.....
I had the APR stage I tune, fairly noticeable improvement over stock. Then went to the stage II after I installed the APR fuel pump. Another noticeable increase in torque and HP. Installed the Meisterschaft exhaust with a Billy Boat DP and free upgrade to the 2+. Impressive increase in torque from 2000-2500 where the stock TTS is a dog. In short, it's worth it. Not sure the cost of Stage III is but can't speak to it as I've not driven one.
