Default Boost issues...Advice welcome.

So car was running great and boosting how it should be @ 13psi. I decided to put a custom 4'' intake pipe tube and do away with the plastic one. I have methanol dual nozzles and they were mounted after the IAT sensor, but decided to go ahead and mount them before the IAT with the pipe. Well got everything mounted and fit just right, but now once I hit about 7psi the car falls on its face. doesnt throw an engine light, has plenty of fuel pressure. So im not exactly sure if moving the methanol somehow is making it fall on its face but it starts spraying at 8psi and thats when the car takes a ****. anyhow. anyone have any issues like this ?

Sounds like you have a boost leak and the methanol is drowning things.

If boost leak test finds nothing, you need a wideband and street/dyno time.
