Where to begin?

[86saleen13]

I have an '86 Mustang 5.0, Speed Density, SN89 SC w/6 psi @ 5700rpm. I have NO monitoring equipment at all - actually I just ordered my boost gauge. I put a coolingmist 150psi kit on my stang a couple days ago and ran about 64oz of water through it. The WI starts injecting at 2750 rpm. Today I mixed 50/50 Meth and water and put in.

I have no knock alert on the car. I am getting some detonation at about 4300 RPM in 4th gear/ with 12 deg. of timing. I have backed the car down to 10 deg and will drive it again later.

Now as for tuning - where do I begin? I read alot of posts and its all strange to me. I dont have any idea what all your terms are (EGT, AFR...) I am going to order the MSD Knock Alert and a timing retard - this should help out. And what about spark plugs and MSD ignition boxes? Will these help detonation? I read about cooler plugs - can I get at autozone?

I could ramble on for along time about this - so confusing :shock:

HELP!! :?
