i would miss gears while spraying my 92lx with 160k on it. id be hitting 8 or 9k befor i new what was going on. motor took it fine. id also spray as soon as my foot was off the clutch when launching. drop it at 3k and go. im putting my kit from my fox onto my bullitt and for tuning im going to do it myself and an sct tuner. its not to hard to do yourself... as long as you have wideband. i strongly recomend getting wideband.GR33N MCQU33N said:Trust me get a tune and be careful when you spray. My buddy with a 90' GT that has a stroker motor blew his block in 2 and spun the main cause he was too cheap to buy a window switch. Long story short it sprayed way too low and calamity! Be smart your playing roulette otherwise.
