I am the owner of a 2001 Toyota Tacoma with a 1st generation supercharger, TRD headers and a AEM Brute force intake. I have recently noticed some degradation in boost pressure over the last few months and was wondering if you all had some insight into some areas to look for problems. Currently the boost gauge is only registering about 4-4.5Lbs of boost when I push it as hard as possible. I was pretty sure when I got it that is was putting out more like 5-6psi when I got the Truck. The car is equipped with the TRD dynamic tensioner and I just replaced all my belts, washed and rinsed all my pulleys, and checked all my lines for vacuum leaks when I noticed the low boost pressure. The TRD installation manual claims that it is supposed to put out 7lbs psi. What kind of boost ratings are you all getting and where else should I look for issues? The PO claimed that they had the whole supercharger warrantied approximately 30,000 miles ago but there was no paperwork to prove it. The truck runs/drives/idles just fine. Any help or suggestions would be great.
