What is your fuel pressure set at?

WHOA!! Talk about helping me out! Thanks man. I am having the same problems. I put all this $hit on my car and so far I only dropped 2 tenths in the quarter. I was detonating at high rpms so I dropped my timing down to 9! And it still detonates sometimes but not hard. I am using 92 octane also. I figured that It was running lean so I got the FPR and bumped the pressure a little. It seems to have helped, Im gonna try and get some more timing out of it now. Since you had the same problem Im probably going to get injectors too. My cpu seems to be taking the cam fine but this thing REALY needs a dyno tune w custom chip. I even put the larger ratio rockers on to get more lift. I am still using the stock heads and intake. Are the motorsport 19 pound injectors the same as crappy stock ones? Summit sells Ford racing 19 pounders and If they flow better than the stock ones I will get them since my MAF is already calibrated for them. I REALY dont want to have to get a new MAF again. Please let me know and thanks for your help..Jesse
