I give up!! don't know if this is a boost problem or not, but I'm getting good boost reading. Just that my car doesn't pull that hard when I'm getting 10lbs of boost, and the throttle respond are so bad and laggy. I can't even pull away from a bpu Civic dx.. wtf.. I hear a hissing noise coming from the driver's side around the brake booster, but couldn't find anything.... What could be the problem, I know I getting good boost shown, but why am I not going anywhere....

 

Do you get transition at all? Perhaps your secondary turbo is not coming online.

Also, make sure your car is at operating temp or it won't allow you to boost completely. Unless my car is at 80*C or above it's slow... Above that and it's like the car wakes up.

 

I'm getting good boost shown on my gauge, even during transition. Just that the car is very laggy and throttle respond is really bad, I have to kind of step hard on the pedle to get the car going...Before I hear that leak, slightly tap on the gas and I could feel it, even on low rpm... I thought it's my intercooler pipes and couplings, so I upgrade to fmic, but nothing...

 

how long has it been since your spark plugs have been changed? you might check those first then move on to fuel pump and injectors.

 

I change my plugs like 3,000 miles ago, and planning on changing them right now.. I'm kind of thought of fuel pump and injectors, but I'm getting good mileage. I'm also running very rich.

 

does anybody have an idea why theres a leaking hissing noise coming from my dash or driver side, like somebody slash my tires?
