[QUOTE="Ninety3Coupe, post: 11409511, member: 127711"] Just got done installing the FPR and the gauge. Doesn't look like it fixed the issue completely however. I set the pressure at a number of places with varied results. Right now it is at 55psi with the vacuum line attached. From what I've read that is way too high, right? It seems like it is a bit better but still not 100% right. I tried down to 35psi with the vacuum attached. 35 ran the worst by far. I finally set it at about 55psi with the vacuum attached and it has run the best so far, but still hesitates a little in the low end. It kinda feels like a car waiting to come on boost (obviously mine is N/A however). Here is exactly what it does. If I roll into first gently and slowly and then early shift into 2nd and then floor it, it will start to go, then hesitate, and then when it hits close to 3000-4000 rpm it goes like a bat outta hell and all seems well. It seems to idle a tiny bit smoother. I checked and rechecked everything looking for a vacuum leak since I had to pull the TB again. I see everything connected and all is well. Everything was triple checked and torqued. Any ideas guys? I am damn near outta the Xmas money now and I miss driving my car. I would love any and all input! My work car is a Prius for Christs sake, help! [/QUOTE]
