i just put on my new afi turbo setup on my b18c. im having problems with the car. its not tuned yet, its goin to be tuned thursday so im trying to fix all the kinks. the car kinda sputters when it goes up in rpm's. it lags and feels sluggish. i tried to kick it into boost and it makes it to 1 maybe 2 psi and just sputters. wont go farther than that. im guessing its a fuel problem? new walbro fuel pump.

its sputtering becuse its not tuned. what injectors are you going to run? and that motor wont last long at all if you keep trying to "kick it in boost" with no tuning

your throwing A LOT of air and not a lot of fuel to it. lean lean lean. and lean is BAD

well my wide band looks fine. what should i do sir?

you should not drive the car until the ecu is tuned correctly. where are you located? you need to at least get a basemap on the ecu. its hard to say if there is actually a problem other than what I mentioned. are you running stock injectors?

its running stock injectors till it gets tuned cuase i dont think it will run off 1000cc injector dynamics till its tuned. im located in charlottesville va.

does the car idle ok? this may sound a little weird, but disconnect the charge pipe, bov vacuum and wastegate vacuum, and see if it runs ok like that (n/a)

unless the motor is built and you plan on running upwards of 15 psi or more, why r u going to run 1000cc injectors? and the computer wont allow the injector to add more fuel unless its programmed to do so, so the injector size doesnt matter as of now.

so your saying i could throw the 1000's in and it would run?

i have another ecu that is chipped and socketed the tune on that is for 10 psi, should i throw that in and see if it changes whats goin on with the car or just wait till it goes to the tuner?
