you will definitely need to retune (i guessing you have a MAP ECU). i ran a T-78 on stock fuel on the stock map initially. only boosted in 2nd gear for a second or two and my wideband went lean in the range of 12.5-12.7. MTR's map is a good start for a single on stock fuel. its safe( rich a hell, at least for me) and you can tweak the map if you have a W/B.98bpu said:i am replacing my twins with a t78 kit this weekend with stock fuel will i need to use a different map?????
