Boost Spikes when Cold

[Benderama]

When driving my while the temp gauge is cold I get misfires that cause my boost gauge to read in the 16-18PSI range. I have my boost set 10PSI. I have gone through all the tune procedures and have NGK Plugs and Wires. The only thing left on the car that could use replaced is my air filter. How can I improve the cars behavior when it is cold like this?

I should also add that I am still having some hesitation in WOT runs since I performed a large tune up on the car and have some squealing coming from the front end. I have checked my belts and they don't have excessive play in them which leads my to belief it may be my Alternator but I am still looking into that.
