So I've had my 06 A4 for about 2 months now and coming from my background of modded cars I just couldn't live with a "stock" car any longer.
I had a great experience with the Unitronic flash on my 07 GTI with about 60,000kms of trouble free spirited driving.
I have been dealing with SEM Motorsports in Toronto since about 2000 on two previous cars... great price and service (shamless plug) www.semmotorsports.com
I opted to get the stage 1+ (93 oct) tune on my Audi. The 1+ gives 18psi vs 16 psi on the stage 1 (91 oct) tune.
First impressions were great after the flash, as there is an immediate difference in power delivery.
now after 2 days of driving the ecu has adapted and the car is pulling like a "frieght train" in the midrange compared to how it use to. Biggest difference would be in 3rd and 4th gears merging on the highway and such.
Also I find that cruising on the highway now at 100-120km/h I don't have to downshift to get power to pass. TQ is there now.
So Unitronic has a happy repeat customer!
P.S The person who got my 07 GTI lease return got a free Unitronic chipped GTI :)
Pic of course as every post needs a picture.
