one thing ive noticed no one has seemed to mention throughout this thread.... is tires and suspension
im no drag queen, but i do know that shit tyres and stiff coilovers wont get you the figures you desire down the track, no matter how much power you have!
TIRES TIRES TIRES! - get good ones, not only are they gonna get you better times down the strip with better 60' times obtainable, but they are good insurance for daily driving, remember they are the only things holding you onto the road!
also what suspension do you have?
....lastly who the hell is your mechanic? because even my mum can tell you that fuel pumps dont change afr's unless the old one was dying, and she certainly wouldnt recommend putting in the old dying one because you're not happy with the extra richness!
