Limp mode or something else?

[Rumcajs]

Last night I hit limp mode. Made 17 psi in very cold dense air. One annoying thing about my setup is that I get cold limp often till the engine is up to normal operating temperatures. What's the criteria for cold limp mode?

MAF voltages are usual culprits, need to see if you are exceeding 3.7 V bellow 2,500 RPM or 3.99 V bellow 3,000 RPM.
One thing you do need to consider is the so called boost spike, anything over 17.9-18 psi and you'll get instant limp.The trouble is that this has the tendency to happen in 3rd gear uphill under the harder acceleration. I can almost reproduce it in another words I know I need to back off a little once I hit 2,700 RPM. Back off Dawes so your max spike doesn't pass 16 psi.

Cheers
