Hi guys, this is the first time I've started a topic on this forum so forgive me if my forum etiquette is out of whack! I am in need of some information and recommendations with regards to a flapper mod on my BA MK2 XR6 Turbo. I've been quoted $1,000 to have the flapper mod done by Xtreme Ford Tuning in Perth. I've had all my work done by these guys and although quite pricey, I'm very happy with the results. (currently running a little under 320rwkw with 4" dump and 3.5" single, ID1000 injectors, fuel pump, 12lb actuator, bolt on cooler, growler, valve springs, and a few other little bits and pieces). I need the flapper done because with the current tune from last week (tune needed after putting on new exhaust) the car is over boosting. I have read around and some people have suggested that to save money, it is easier to put on an external gate instead on the flapper mod. This I'm not too keen on as I'm planning on buying an under battery cooler kit later on down the track and would require unnecessary mucking around. Doing the mod myself is also out of the question as my mechanical ability does not extend this far. Basically what im wanting to know is, is this worth $1000? Will I need a retune after doing the mod? Is an external gate a viable option? Should I be expecting any power gain from this? Any help or opinions gratefully taken on board. Matt
