Adam Not everyone has the experience that sound's like you have, rather than starting a bun fight on the net that as we all know (and you'd know if you frequent PF) ends up going nowhere why not explain to the person that they've been misinformed. Attacking somebody the way you have in the last few post's is leading no where and making you look more of a dill than PSI40L.(no offence intended). Dont drag this forum to the gutter like so many other's have been it just end's up being a pathetic waste of space, as you can see this thread's gone to the dog's already let's hope it's a one off incident. There's always PM's if you want to get personal rather than have everyone else having to read your problems with that person. Personaly i'm on a major learning curve with the purchase of a Turbo and i want to get as much info as possible, if somebody post's something i listen to what they have to say but dont take it as gospel until i know it's fact and has come from a reputable source. What got me on the soapbox?: In my eyes you are just as much a 'backyard expert' as anyone else here im afraid, till you prove otherwise. Please tell dont take offence as i said i'm here to learn and you may be one of the ones to teach us.
