Flat spot and top end power

P

Hi i recently had a engine transplant in my 2000 p2 gti, because i ran out of oil and completely ceased the engine so i decided instead of rebuilding the engine i would just drop in a replacement it came out of a 98 gti. It runs ok seems to pull better then the original engine but has no top end power doesnt pull after about 5700 rpm and has a flat spot around the 4 rpm mark. we advanced the ingnition timing as far as it would go and the flat spot went but it still has no top end power. Then i got the car dyno'd to see what power it was actually putting out and to see if the fueling was correct he said the fuelling was perfect and the car was putting out about 90kw at the wheels which is near enough the standard power. is it normal that i can run with the timing fully advanced without it pinking and why it had no top end power?
 
standard timing should be around 15 you say its advanced all the way what is it set at?
 
well at 15 it had a massive flat spot so it was advanced 2 degrees and improved abit and just kept advancing it will till it couldnt be advanced anymore, not sure too what degree is now.
 
s'ok, id be amazed if he set it into timing mode, what with him lacking the knowledge of how dangerous fully advancing the timing can be
 
Dave - since you are in the north east you should speak to wezz, he sets the timing for most of the AOC :) he may be able to help you out.
 
doesnt need to be in timing mode to fuck things up, turn the dizzy enough and it'll sound bad. you can do it by ear, obviously you know that you dont need to rotate the dizzy much to change degrees

i thought the ECU resent the timing if it wasnt in timing mode?
