can't boost

[Yngvar]

sorry of spelling and grammar
It seem that as soon as my car tries to boost it hits fuel cut. I have boost leak tested it and fixed all the leak and it does the same thing. The car use to boost before my caps leaked in the ECU it would hit fuel cut there to because of all the leaks. But now after I got my ECU fixed now the car won't boost at all it may make like 2 pounds but thats it. It hits fuel cut at 4500 rpm which before it was making 10-15 pounds of boost under 4 grand What could this be please help

Your saying two completely different things here. 1st off you say your ecu had and issue and 2nd your car won't produce boost. I know this may sound dumb we need more info.

Need a better description of the problem. Did they reset the ECU after repair? ie Clear codes?
is the ECU for a Turbo car? DO you have a air/Fuel gauge? it's good to see exactly where your fuel reading is dropping off. Give us a better description of the problem and stay in order of events (What went bad when)

looking at your mods and assuming you covered the basics. You may want to double check the ecu, or have it tested.

Well my car was doing the same thing with the fuel cut type issue. Didn't change out the ECU or anything like that, but I checked for boost leaks and couldn't find anything and it sill did it. Finally thought maybe the turbo was shot, so I took it off and took the turbo apart and nothing. Finally put it back together and took 5 minutes to change the plugs and it boosted fine ever since. Just tryin to help ya out a little and possibly save ya about 190 bucks so ya don't buy and ECU and it just be plugs.

It starts out my car had boost leak but is would boost for 10+ pounds. When I go to drive it into my garage it won't start because of the caps leaking. I send off my ECU get it repaired get it back put it into my car and take it out for a drive. Thats when it started it seems to hit fuel cut at 4500 and it dosen't make boost. So I boost leak test the car and find a broken coupler my shaft seals are leaking and some loose clamps. After fixing all this stuff I take the car back out and it won't boost much pass 2-3 pound and hits what I think is fuel cut at 4500. What could my problem be?
