Sam, I can assure you Trent knows his stuff.
I personally put him at the top of my list when it comes to tuning my engines and also my close friends engines. Having been to a fair few tuners I would only let two of them touch my engines and Trent at Status/Chequred tuning is usully my pick as he is much more willing to help/give advice then my other opton.
They are'nt the best when it comes to phone communication though, which number are you trying to reach them on? Trent pretty much wont ever answer his mobile, its always best to call Cats mobile (0414 944 146).
