Hi, just signed on to this site cos today I installed my flash tuner.I have a XR6 T ute.No other mods except 18 inch mags.I have been reading some older reports on this site about peoples experiences and they got me quite excited. But after installing 8psi tune I felt a little let down,sure I could feel a bit extra and could hear the turbo whining,but I was expecting to be blown away after hearing other peoples first experiences.I live out in the country so I was able to give it a good squirt. It felt like it was pulling harder but when I caned it up the hill outside my place it still only got to 140kph, same as it always has. I also thought it may break loose(smoke up) when I floored it from a standstill,but NAH! Was I expecting too much? Or is this how it should go on 8psi? I wanted to try the 10psi tune but am only running 95 octane fuel,could this do any damage or be part of the problem? any help would be appreciated.
