hey ive finally decided to get my ba xr6t tuned! The guy that has been recommended to me has told me what to do before I take it to him, ive already done some mods (fmic , highflow cat, atomic valve springs, plugs and coils) and he is saying to put 1000cc injectors, mod the wastegate flap?? and fit a 12pound actuator spring before I take it for a tune. I can find the flaps for sale but have not found any info on how to go about modding the flap, I was wondering if anyone can shed light on this or point me in the right direction any help would be welcome
