Has anyone heard of problems running these injectors at boost
of over 25lbs on these injectors with them sticking any help
welcome thanks.

MSD injectors = Delphi Injectors, many people have used them.

They WILL have problems at very high fuel pressures. 100psi will cause problems, but keep in mind that this is *differential* pressure. Meaning that if you are running 25psi of boost, you'd have to run ~125psi of fuel pressure to create problems.

I've tuned many vehicles using Delphi injectors with no problems. I believe the problem arises from the ball & seat injector metering - It's not a disc, nor is it a pintle design.
