'+25BHP +21FT/LBS OBD-FLASH Developed at the request of our Audi RS5 customers, this ECU Tune can be set up at customer request to induce pops & crackles when revving and on over-run in gear, as well as improving power output and delivery. Our method of inducing pops & crackles replicates what other manufacturers use in OEM calibrations, which has the added benefit of valve cooling, preventing warping. Due to the relationship to torque demand, the pops & crackles map can produce a slightly (milliseconds) throttle delay at certain load values. “I took the car for a proper hard run. I am very pleased with the smoothness and increased power. It is very noticeable.” “It's been over 8 months since I first approached Team VAP for the tune and I have been enjoying it as much as the first day I installed it!! I haven't seen one negative review about it, and as Stuart mentioned many are switching over from APR and can confirm that it is much better in every aspect. The sales #'s and social media support from REAL VAP TUNE Users is unanimously positive. The team at VAP was a pleasure to work with, thanks again I am loving everything about it almost a year into it.” Includes hand-held programmer.
