I have had my regular cyborg tuned by Russ, Adam and Ken at OZ tuning.....Russ could not tune my cyborg period. No more will be said. Adam, saved me a shit load of money and was able to tune the shit out my cyborg. However, at 24PSI it was "maxed out wastegate duty cycle" So I am told...I tried Ken, he turned it up to 27PSI and it felt about the same as Adam's MAYBE a TINY bit faster uptop. However, we had an issue where he could not tune my TIAL Q BOV to work at all. So I am stuck using Adam, Car pulls hard and feels good, I had him look at another log and he told me I added fuel to my car because there is more room, Funny, he no longer sells the X37 and now my cyborg magically has more fuel and he can turn it up some more. I am saying, he might of held cars back because of the X37, Is he doing it now? I have no idea....But this is just my 2 cents..
