I'm using emanage blue with larger injectors, car runs fine under vacuum and idles normal also.

But one i start to boost, check engine light goes on. The voltage reading on the MAF reads 3.0 volts when the CEL turns on. Are the maf suppose to read up to 5v.

Thanks.

nope its not clamped because i want to use the 4 larger injectors (4x400cc), and if i have to clamp it id have to install a 5th injector to activate after the clamping.

How do i fix the problem without having to go with the extra injector?

thanks.

you need to condition the MAF signal to run larger injectors. you'll also need to retard timing

havent had time to bring the car to my friends shop to have the obdII scanner read the error, but is it possible that the error is coming from the map sensor and not the MAF sensor?

if there's a MAP sensor on this engine, yes.
