I just turbocharged my car but it wont rev past 4500 when boosting. It feels like its leaning out so I changed my fuel pump. I put a walbro 255 in it. But still nothing. My setup is a b16, T3/T4 turbo, turbonetics evo wastegate, fmu with stock injectors and the fuel pump. If anyone has any info please let me know.

 

alrighty u have any fuel management or map fix anything other than what you said?

 

sounds liek a map sensor issue because of no missing link

 

I will sell you my missing link for $40.00.

 

im having the same problem with the turbonetics kit

 

but i have, fuel managment, had it on a dyno, new fuel pump injectors, closed the gap on the spark plugs
msd ignition it has been getting better but not perfect....

 

Fuel management = hondata or Uberdata or AEM...
-or-
AFC hack
-or-
FMU + missing link for MAP sensor

Which one?

 

any cel's? maybe the car is trying to go into limp mode for some reason.

 

thats what i was thinking that maybe that knock sensor is picking up some vibration or somthing like that i was told how to put rubber around the knock sensor to make it not pick up vibration as easy, idk tell me what you think

 

Check your plugs..see if your leanning out after 4500...

 

i have had my car on the dyno and it leans out a lil bit aroud vtech but only for a couple of 100 rpms

 

hurry and Edit your vtech to VTEC!! before it gets bad.

 

Did this started happening right after the dyno or out of nowhere? Also, how much psi are you running on ur set-up?

 

it happened rght after the dyno it was fucked up

 

get 450's and do afc hack...

 

i have the bigger venom injectors and the fuel managment that came with the turbonetics kit
