APR releases preliminary data on their B8 S4 chip upgrade

APR has been talking about their progress with the B8 S4 chip tuning program but we have yet to see anything of substance to back this claim up. That was until today when APR CEO Stephen Hooks posted some exciting dyno charts on the QuattroWorld B8 S4 discussion forum. They show an astounding 70+ wheel horsepower gain at redline and notable gains throughout the entire rev spectrum. It is exciting times for the B8 S4 crowd and the anticipation of new mods coming out reminds me of late 2000 when the B5 S4 was going through a similar phase. APR has already developed and released a nice exhaust system and have been working hard for months on end on perfecting the chip upgrade.

Having driven several B8 S4s in stock form, I can only imagine how perfect the cars must feel with this extra power, especially near the top of the rev limit where the car seemed to fall off a bit. These cars are extremely potent out of the box and with this extra horsepower they will be even more impressive. Pricing and availability are not available just yet, but I would expect an ETA to be announced soon. Yeah, I know… “2 weeks” right? 😉
