Ok Im still with my gorgeous sexy wonnnderfulll SRT6 . My love, My life.

HOWEVER Im getting a little bit bored now.. I wish it to be faster. (I suppose now that its been with me for 6 years, I might be used to performance, so Ive hit a plateau)

QUESTION: How do I make it faster? I would appreciate 'reality' over 'fantasy' as I have set aside a budget to make changes - permanent road-legal changes.

The most important thing is, if you are going to chime in on this, please remember that I am in the UK, not USA - so a little british skill/FB/tuning Links would be appreciated!!

Ive spoken to a few guys, and they all say "upgrade??well you won't keep it straight, it will be all over the place" - a fair point, as it is very skitty with trac on (ive spun it on trac off a few times)
(my goal to get SRT6 under 4 seconds, oh please God This would be awesome)
