Given the different opinions, it's safe to assume that different mods have varied results on fuel efficiency? Eg, a CAI would improve power and fuel economy, but upgrading the fuel injectors would not only improve power/fuel economy (when cruising atleast), but unlike the CAI it would also allow the engine to consume more fuel when thrashed? What about a retune, exhaust system, etc?

Thanks for all the reply's guys! Hmm, well then does that mean that there are no modifications that increase fuel efficiency whilst delivering more power? Ie produce more power given the same amount of fuel? Not fussed about any environmental considerations. Given that a stock car must adhere to emmission standards, and is tuned accordingly, can it be retuned for better fuel consumption AND more power? Or is that an oxymoron?

Hey all, Had a good read over this forum, found some very good info! Especially liked the 'Mods to Power Comparison' and 'Modding your FG XR6T' threads. But when it comes to fuel consumption/modification advice, I've read too many conflicting arguments on the web, so I've come here for your advise! Looking to purchase a FG 2010 XR6T, would love it to sit between 250-300rwkw, but I don't want to be paying through the nose for fuel! If anyone could comment on how each modification (from knowledge or experience) affects fuel consumption, that would be greatly appreciated, especially in concerns to the FG XR6T. Thanks in advance :-)
