I think it's important to clear a few things up in this thread. The first and most important is that Lozic is a 100% truthful, well intentioned person who in all my experiences puts his customers 1st. I was the first person in North America to run a Lozic tune and have had hundreds of interactions with him personally and to help other customers due to language barriers. He goes out of his way and often at his expense to make sure we are happy, even when it's our mistake! He doesn't play the blame game and is only interested in making you satisfied with your tuning experience.
The second thing is that he has a massive wealth of knowledge and really knows tuning at a level that most don't. I think where the problem starts is that Lozic offers an almost unlimited amount of options/combinations and is interested in exploring any avenue a customer wants. Western based tuners know that the safe road is to create a few off-the-shelf tunes that have been fully tested and are "safe". This is because a high percentage of people who ask for tunes, have little knowledge about how they work and tend to get themselves in trouble quickly and then blame the tuner.
What's got me a bit troubled is people blaming tuners for overboost, that they believe is causing head lift. As I understand it, head lift is caused by exessive cylinder pressure - which could be high boost but could also be lower boost and high ignition. When I spoke with Lozic he advised that not one car that he has tuned has had head lift
when just running the Lozic ECU. I know many use piggy backs to log (and I did too) but it's been proven that piggybacks can impact the ECU and even cause values to be written to the ECU (such as
EWG control).. so it's really not fair to say a Lozic tune broke my car when there are other factors at play. Lozic has customers who run high boost and very high load on 300kph runs with no issues. I don't know enough on the subject to have an valid opinion but I do know that sometimes we tend to think we know more then the doctor because we "googled it" or heard it from someone who "thinks" they know what happened.. We goto Lozic because he offers great tunes, great pricing and a wide variety of options. However that felxibility bites him when we select options that we don't understand or thought we would like... We can't have it both ways. We can have it safe or felxible but not both.
