hi,
i have a 2004 f150 4.6 V8 with 27000 miles on it, i recently deuled the exhaust (true deul) with 40 sreies flowmasters also dumped. i also have a cold air intake. my problem is now my truck seems even slower than it was before, it feels like when it shifts its nice and powerful but after the shift it really bogs. anyone have any ideas what i could do to fix this?
