Our customer just got done putting his new VR Tuned Auto Flash on his BMW 328I coupe. The Auto Flash also known as the TCU flash, loads snippets of code to the car altering the fueling and timing while improving upon shifting and rpm performance. The TCU Flash units as described here, have under gone extensive testing on the dyno and even the Nurburgring to prove their performance. Our customer reviewed this product by saying, “Mpg appears to be a bit better. R P M seem to pull steady throughout the range in each gear. No r p m fluctuations at idle. A bit stronger through the mid range r p m. A stronger finish at the top of each gear.” Check out all the TCU Auto Flash Kits available here.
