i have a 95 civic dx with the sohc v-tec and i recently turboed it. i bought a bigger fuel pump, new fuel rail, new fuel pressure regulator, and a vafc. i havent got the car dyno tuned yet but i moved it around my driveway today and whenever i touch the gas it leans out really bad. my question is if i take it to get it tuned will the tuning fix this or is there another problem???
thanks

how do you know it's going lean? make sure the vafc settings are correct (4cyl, wired correctly, etc.). tuning should correct any problem ... but I stress should. it depends if everything was installed correctly or if there's any issues with the car in general.

 

i have an air fuel gauge, i'll double check the vafc because that should tell the computer to dump more fuel right

 

Air/fuel gauges are not accurate or good for measuring ratios. To accurately measure your a/f ratio, you need to use a wideband o2 sensor (available at any good dyno shop or you can purchase your own0>

 

Agreed 100%. You can't tell jack from one of those Air/Fuel gauges. I know, I owned one for a while. Get it on the dyno and figure the problems/fuel out there.

 

i found out the problem and it is that the people who installed my vacf didnt program it, and i looked through the book today and you have to set the air correction and the fuel correction, if anyone knows how to do this get back at me
