detonation? fuel cut? HELP

[GS><]

Well folks I have more problems, all of my mods are in my profile. My big problem is that when I boost over 5k it REALLY screws up. I am no expert on this kind of thing but it is definatly annoying. Here is a break down, when I start the car it doesnt wanna idle, it just tries to stop, kinda annoying but i can deal (this is prolly cause by not having a engine idle motor any more or maybe cause of removing the egr). ANYWAYS, I have a 1g head and cas so I had to time the car and when the car is still cold I am not getting consistant flashes from the timing light. But this happens ONLY on the #1 spark plug. I changed the wire for #1 and that didnt do it so i changed the ignition and that didnt do it. Once the engine heats up everything with the light is fine. I know that I am supposed to time the car when it is up to temp so dont give me any "you are an idiot" speechs. I have checked everything that makes sencse and I am wondering if ther is anything with the safc2 that i can do that will help or if there is anything that the datalogger can tell me. I have done a couple of runs down the road logging and the timing is really going all over the place. Here is a really stupid ques, could i have the cas 180 out? I am looking at the log right now and every time that I rev up the timing goes down. I really dont know much about this kind of thing, as far as timing goes, I just got the logger so I am not up to par in operating it. I looked on thier page but I always seem to have a problem that noone has. The only thing that makes no sense to me is that it idles like a DREAM once it heats up, no noises, no choppy idle, sounds like new. Well sorry for the long post wanted to make sure that i gave as much useful info as possible. Well thanks

Have you tried swaping plugs around and checked the gap... May be too little to trigger your timing light when cold.

It is possible to install the CAS wrong. On the end of one of the blades there is a large stamped mark if memory serves me correctly.

The rough idle could be the spark plug heat range or the gap. It could also be the temp sensor in the tstat housing is getting ready to die. I don't think a missing EGR would be coming on during warm up so may not be a factor.

Anyone else want to jump in here?
