i just got my major service at ultra-tune, taringa, and when i picked it up they openly admitted that they knew very little about the rb25 engine. I then hopped into to the car and started it and it was idleing at 500rpm then 100rpm and then 500rpm and so on. I then took the car for a drive and boost was maxing at around 1psi and under full throttle the car would splutter and i would lose all power. i took it back to them and they were clueless. they tried to tell me that it was because the ecu had reset itself when the battery was disconnected and the probelm would sort itself out in a couple of days. i called up 4doorz and we looked at the engine and the d**kheads haden't hooked up the lines to the carbon canister. we put them back on and the car is now running sweet. I would recommend that people take their skylines to places that genuinely know skylines and have the proper knowledge. I will definately be taking my car to Gavin Wood from know on as he seems to know his stuff, unlike other places around Brisbane that "reckon" they can do it.
