Thought I would update this for anyone whos interested.
Havent had it RR'd yet but the following has changed (we cant ever just leave a car alone can we lol)
Mines ECU (advanced timing, rev limit raised to 8.5k, other things adjusted)
Splitfire DI Coilpacks (original ones were knackered)
Grounding kit
Mines Boost gauge (looks ancient, so it will go well with the interior when I get a gauge pod)
Defi HUD (displays RPM or MPH/KMH backwards onto the screen so you see the reflection)
Japspeed 3" mandrel cat back with 4" exit (deafening)
On whole, runs nearly perfect, never fails to put a smile on my face and scares the shit out of me. MPG is about 19-20 now with the changes. Plenty of pops and bangs etc
Next on the cards is some brakes that actually work (funny how alot of people dont justify £300 on discs and pads but will on a new exhaust - ive put it off for ages)
