fuel cut /or losing fire

[freeman 188]

I have a 91 laser ,with greedy 18g turbo ,255 fuel pump ,450 injectors ,and so on .my problem is when it goes to 5k to 55k it suddenly shuts down until I let off gas running 14psi boost . didn,t have this problem with the 60 trim just slow spool ,any help would be appreciated

When you hit fuel cut you lose spark aswell.

Also unless you have an auto 450cc is the size of stock injectors

my car use to be auto but I changed it over to manual , about a year ago ,do I HAVE TO CHANGE THE ECU also or would it be worth the trouble

Yes you have to change the ecu.
The auto ecu is setup for 390cc injectors.
You might want to look into changing your cams as well.

THE ECU I HAVE ,but the head went onto a 2.0l non-turbo and now it is sold , I guess I should have kept it ,that is what happens when you try to help someone out ,you always need part,s when there gone , what would be the advantage of going to a 2.3 stroker ,
