I plan to pick up a tactrix cable in the next few days in preperation for going stage 1. I spoke to Eric over at toquedperformance via e-mail the other night about getting a custom map made for this purpose. He highly suggests that i pick up either a MBC or an EBCS, as he says the stock boost control system on the 04-05 wrx's is almost not worth doing a tune on. All I really want out of stage 1 is a more linear curve with some more meat under it, is an aftermarket boost controller necessary? If so which should i go with a MBC or a EBCS? I like to do things right the first time so any opinions on the matter will be greatly appreciated.
One of these days i'll make a real signature....
