I'm going down to see Bill on Friday to finally remedy a boost leak and to have a 3" TIP and Jetex filter fitted. My cars had a custom Jabba map applied and has the bhp/torque that's displayed below (standard airbox and TIP). I can't wait to see what impact the TIP and filter have on it Obviously all rolling roads are different so I'm most interested in the effect on the curves, hopefully the mods will help sustain the power for longer towards the top end. I'll post up the results after Friday. I'm so excited I couldn't resist posting! Dave.
