Yesterday I was fortunate enough to have my R53 tuned by Nastase Adrian and he was a great joy to deal with. My car is now pulling MUCH stronger through the entire band to the point my wife whose idea of a car is basic transportation said to me "The car seems faster...what did you buy?". I couldn't be happier as the car even idles better. Thank you sir it was a pleasure to deal with you.

My engine mod list:
2004 R53 JCW
Forged short block (Wiseco pistons, k1 rods, king bearings)
Balanced crank OEM Main Bearings
RMW Big Valve Head
RMW Grand Am cam (264/272 deg duration and .400 lift )
550 injectors
17% Craven Speed pulley
GRS motor sport InterCooler but will be switching to the GP this week
RMW Shorty header
Miltek exhaust
Innovate gauges (AFR,Boost, and Oil pressure

 

I used Adrian Nastase a couple of years ago and had a similar experience. At the time, I had 50,000 miles. I now have 180,000 miles and have not had an issue.
