Sorry i thought yours was over 270. 271 or something like that. I think i might have got yours confused with another ISF, as the latest one Sonny posted on his FB page, im sure was 270ish. 270 seems to be the magic number give or take a few kws for an intake, catback, cat exit expansion and tune. Only seen LTuned with alot more due to his headers but he assures me, he is fitting a supercharger next week and is aiming for 350 @ the wheels lol (sitting back with popcorn waiting for his reply haha). Ps if you find bargain performance headers, please let me know.

Definitive advice from Lexus Customer Assistance Centre received 10 May 2017: 1086 IS-Fs were sold on the Australian market, LCAC were unable to obtain annual sales sub-totals. More than I anticipated, but that was based old thread ref above and what I heard from a dealer once. Interestingly ever since I began looking around 2013-14 I noticed there are consistently 35-40 IS-Fs on carsales or ~3.5% of the total pool of cars in Australia.
