Thanks for the info stu,I like the punch in gives,but at least i know its normal to run out of steam when it does,I may try a bigger housing, as its a pretty simple change if i don't like it.Are air injectors a simple plug in,(just for a bit more control?)then you alter the map to suit.i'm assuming for complete control i would have to use an aftermarket controller(Don't want to go down this route,as its a bit much for the odd track day,and a sunday blast).
Oh,do you have to alter the chip for a .63 housing
thanks again stu
Matt
