As you guys know, I have recently purchased a 06 plate exige S so believe it must be the 220 version. Could you tell me what was invovle to get the power gains from the 240 version?
Also if I were to go the gotham route (injectors and remap) what sort of power output should i expect?
No point in going to the 240, either the Chris Neil 260 upgrade or the Gotham is the right way, the Gotham gives around 255hp and the CN about 260hp, they are both similar in having a remap to fully open the throttle and larger injectors to cope. not sure of price differences though.
As Ade says - skip the 240 & go straight to 260
Not sure on the Gotham costs but the CN,s is around 2.5k
You’ll need injectors, fuel pump, remap and I’d recommend the TRD clutch as well
After that you can go TRD air box, lightened flywheel & uprated intercooler for a nice ‘safe’ 260 ish.
Not sure where you are in the country so that might be the deciding option
If you look at CN,s give Paul a call - top man (for a main dealer) !!! 
REcon Gotham is about �1300
had mine done at what was Sinclares 2.5 years ago and cost me �1100 if I remember.
I’m in essex so only about 40mins from sinclaires /ea. Called them earlier, was told about 1450 for Gotham tune which involves remap and 440 injectors, should be about 250-260 at fly.
Will think on it, sounds good power per cash
with Gotham, 2bular manifold, decat, GT3 box, mine read 257 at the wheels on Owen developments rolling road last year, only got hard copy of readings so can’t post. At 7k power starts to drop off. A good thing to know when driving on track
Komotec - you won’t be disappointed!
Exhaust will be one of the first things on my to do list. Ideally want it quiet at cruising, with a roar under full throttle, maybe a little burble at low speeds?
On full throttle my old vxt used to pop rather loudly during gear change, sounded great
Komotec ? any details?
2bular, there really is little other choice 
Just fitted a 2bular 8x22 oval to my S220. Its exactly what your after, nice and quite low down with no drone, then sounds great when you get on it!
I had a 220S until a week ago when i visited EA and had Wayne fit 440cc injectors, unlock the ECU and map the car giving me 243bhp @ wheels with 164lb/ft.
I’ve got a Forge IC, 440cc, TRD Filter, ECU remap, 2bular 4-1 + Decat and H2 Trackday GT3.
Gives you an idea of what to expect.
Good set of figures
