I’ve met Harry from Navardi a couple off months ago and from that everything went straight upwards. He helped me out with different questions on my n20 engine with lower compression pistons.
Awesome experience, Harrison’s work is remarkable. He did a wonderful job on BM3 custom tuning for my wagon F31 N20. Has excellent recommendations and resources. Without any doubts, eyes closed in trust any tune.
Harry at Navardi Tuned is the most knowledgeable tuner for these engines. My n20 now performs greater and more efficiently; strong, smooth, and consistent!
Perfect job done by Harrison on my BMW F33 420i engine.
Very serious, he spared no effort to provide me with top-level programming. Powerful, flexible reactive with maximum reliability.
I live in France the time difference has never been a problem. Depending on the datalogs produced, I received dozens of updates over several weeks. Excellent follow-up.
Definitely recommend Navardi Tuned!
The most seamless experience, Harry (the owner) is the most helpful person I've ever met in this industry! I recieved endless support throughout the months before tuning, all the way through the tuning process, and a TON of follow up afterwards. Do not listen to some of the other reviews here on Google, they are spreading serious mis-information. They are all missing the fact that the owner of the troubled vehicle acted negligently in looking after a car that HE decided to tune well above factory specs... seemingly very idiosyncratic to a normal person. Regardless of this, if you want your BMW tuned to make it more enjoyable to drive, or to accompany any modifications you have done to it, you couldn't find a better guy than Harry.
