I'll try an upload a pic of my dyno chart, as it has the before and after power and torque charted on it, you can see the difference there as when stock the torque falls away but once tuned it holds it flat. I'll try to upload that tomorrow if you like??? As for final figures kartman is spot on, there are so many factors as to what can affect the dyno reading, most people say 'take it down the 1/4 mile to get your true outputs', so dead stock my car ran an 12.8@109mph and as it is now should easily run an 11.9 pass Also malarkey carries on cause he wishes he had a GS, and I'm actually a nurse hence the emoticons :-) he just seems to like spamming ATM...
