texas heat?

ive got an auto 91 300zx tt with jwt ecu and jet boosts and bolt ons and am having problems boosting 13.5 psi it does sometimes but not all the time it either runs 12 to 13.5 or barely 5 psi (more times it runs low boost) i dont have upgraded side mounts but should the heat make that big of a difference or is something else wrong? already considered boost leak but wanted to hear others thoughts as to what could be wrong..

Upgrade sidemounts will lower your temp and make the car run better at higger boost.. But, your problem isn't the SMIC. Part of your problem is the boost jets and most likely the way you've set them up..

The problem with hitting 6psi, its caused by your ecu. Thats safety boost. run your ecu codes and it will tell you whats wrong.
