Turbo Honda Problem (wrong forum but need help!!)
01 Accord Turbo Lag????
I just installed the T3/t4 Hybrid Greddy turbo kit for the past three days on my Accord 01, 4cyl and everything looked straight to me. I tried to test drive it to see any leaking with slow speed first, but when I step a little heavier on the gas peddle to about 50-55 mph there is a lost speed in my car and there's a weard noise. It sounded like there's not enough air.
.Does anybody knows what's going on?? Or does it have to do with the Vacuum Sources? About the Vacuum sources, i connect the Vacuum source from the BOV together with the Wastegate Vacuum source and used a T fitting and connect them to the engine Vacuum Source (IS that a good idea?) or sperate them to diff vacuum sources. There's a nipple on the Turbo and I was going to connect the Vacuum Source from the Wastegate to it but decided NOT. Well, i 'll try to mess with it again but IF anyone knows what's going on with it, please give some advise cause it doesn't sound and perform right when i increase the power. I have pictures but working on how to put them up here. (P>S) The BOV doesn't make that "psshhhh" 
sound like other's people BOVs do.. I talked to some guy and he said that's a Turbo lag and it happened to alot of turbo car, but he didn't tell me what's the problem is and what is lag? Also, someguy thinks that the turbo may not running or pushing any air into the intake but I've checked to see if there's a leak on the Pipes or if the turbo is running or not and everything was working right...Still don't know what's going on.

Anytime you do a major modification to your engine, you need to adjust the ECU program on a dyno. Only on a dyno can you see the fuel air mixture as well as the torque output across the RPM range and range of throttle position. Trying to tune a car on a street is not very effective.
Otherwise, please explain your problem by telling the RPM you at not the speed. The engine and turbo don't care how fast your going, only the throttle positon and RPM.
To answer the question directly. Most likely the fuel mizture is too rich or lean at that RPM and throttle position you were describing. Either the turbo has created a set of parameters that are outside the adjustment range of the ECU, or it could in fact be a vacuum related problem as you describe. I'd get a service manual and figure out the correct hose routing and what the function of each connection is.
