This sunday may be the big bang?!?!?! !dodge but i have my eye on a 2.9 incase, with a view to major uprating... The kit cost me £250 of a mate (usually £5-600), since then, i have spend £300 on a 2nd 11lb bottle and brackets, £300 on a dynotune, purge kit, switch centre and pressure guage, and £370 on the digital progressor, oh yeah, and £50 per refil / bottle! (i'm up to about 6 so far!!!) but i am told you do calm down after a while...? all in all with the rolling road setup on thursday, around £1500. but to be pushing 300 brake at the end of it... worth every penny i think?? be interes
