Pete,
What DV does your mate have on his STI in Greers?? I may be wrong but it looked like a polished Bailey, only noticed it as i had the blue one on my uk300 when i had it.
May want to give him some advice too []
IMHO.........stick with the original DV's, they are on the car for a reason. Yes i used to have a VTA Turbosmart but swapped it back as it was pump and noticed my oil started to stink of petrol.........may or may not have been due to the DV but it was the only explanation.
