Question Sluggish Acceleration when Cold

Hey Fella's and Fellet's

Ok after recieving my Boxster from the bodyshop, I immediatly noticed that the acceleration was lacking BIG TIME. So i figure since it wasnt drivin in 1 month I filled the tank up with gas and drove it abit and that seemed to clear up the low-mid RPM lack in power... However, the High RPMs (5k & Up) power curve seems to flat line.

Usually when that happens, I clean the MAF and problem solved but this time it didnt work, I also cleaned the airfilter and no change.

Yesterday morning I did notice that when the engine is cold, the mid-high rpm acceleration is non-existant until the engine warms up for about 30 seconds later, then the low - mid RPM power is there again... but still no power past 5k RPM's.

Anyone have any insite with this issue?
