Boost cut in cold weather clmap installed.

[Jarods7920]

Ok i am having a problem latley with getting boost cut in 4th gear since the weather has gotten colder when i try to run 18psi. I have a clamp installed and last night i confirmed its working correctly so i am not sure what is calling this. Max pressure i was seeing is 19.5 and it was a short spike. This started happening after i had my race pipe and exhaust installed. On my low boost setting the car is fine which is 15psi.

What are your mods? Do you have datalogging capability?

It could be loss of fuel pressure, i.e. fuel cut. Any case, at what RPM does the cut occur and after how long under acceleration after your boost spike?

I am thinking its loss of pressure case its only when i run 18psi and its only above 5k that i notice it. I logged it and it showed that fuel pressure was dropping below 1200psi. Mods are 3" exhaust from dp back. Boost controller and a modded stock air box.

Just adjust the MAP clamp down to 10-12 PSI...
