What can I say he's very unprofessional, cocky, arrogant, his work ethic is poor and he has been called out by giving people false tunes for different cars including mine.
Any tuner any real tuner only takes at least an hour to tune a vehicle within the tune time vitviper aka Vitiley Mitchenko takes his time with no reply back or any feedback to safely assure the customer of what's going on instead he's very rude.
He has been known to copy and paste other tunes and making it his own when he never has tuned the vehicle at all. Since when does it take 15 to 30 calibrations to tune a stock all motor car with bolt-ons? In his case forever I got banned from 8th civic for exposing him and the truth most of the moderators are his butt-buddies. If your going to use the flashpro do not buy anything from him. His site is overpriced and his workmanship is extremely poor.
His tuning calibrations are late and extremely poor. His knock count ratio is through the roof and all I have are bolt-ons no forced induction on stock internals. He doesn't keep you updated at all and his communication is very poor as well. He should not be running a business at all. I'm glad he has been exposed time and time again.
