Need some Help fig. out what might be wrong with this evo of mine!!
alright so i leave the track sat. night and car drove great , filled up the car then headed back to my buddys n still nothing wrong..car sat for bout 30-45 min went to change my staging on my rev limiter cuz it wasnt collecting boost ..loaded the map n started the car and now sounds like a suby or harley davison as i like to call it..change plugs sunday morning took out the plugs n cylinder 1&2 plugs look brand new after driving it for bout 10 mi.and 3&4 look white(lean) or atleast look like they were burning ..so that tells me that maybe no fuel or no spark to either of cyl.1&2..so go to exhange my buddys spoolin up Cop and still same result so eliminated that prob. did an compression test went 150 across the board except cylinder 1 was 140..had a friends shop do a lab scope and said ecu and injectors are fine so nuthn electrical im guessn...any ideas on the problem id be glad to hear what anyone has to say . i appreciate it
Wow, dude, learn to spell and punctuate.
On to the topic. Check the gas, I've seen people go to some random discount gas station, fill up and issues start. Emptied his tank and found all kinds of debris and clogged an injector.
Edit: Wow, go me for not seeing the date on this thread..

Could be a gasket issue. Try the bottle test and see:
open rad fill port and flip a 2 litre plastic bottle (or whatever would cover the mouth of the port while car running (don't open when hot of course)
when you do, it should spill and the pressure from the rad should cause it to stop forming bubbles. Once it stops pulling bubbles, have a mate shut the car off while you keep the bottle on the mouth of the rad... if water from the bottle suddenly rushes out into the rad, your gasket may be shot.

I read a thread (sorry I can't recall where I think might have been in the tuning results section).
Anywho, the OP had the same SUBY idle and it was that one of his injectors had gone bad. Not sure if this is your problem but I remember him saying "my car had a suby type idle (no cams), took it back to the shop and they told me one of my injectors had gone out the window".
Something along those lines.
