Just my Z back..... new motor, bigger injectors, fuel return system, crawford plenum and back to stock vortech pulley.....I seem to be running rich at times according to my M-300, would installing the 3.12 pulley back on help in tuning and what belt size is it?

 

anybody

 

What happen to your motor ? Is the new one , built ? More than likely its the bigger injectors that are making you run rich [ what size are they ?]

 

440cc....and no its a new stock motor...didnt have the time to wait to have it built up but I will slowly be building up the old motor and possible going TT this time

would changing to the 3.12 pulley help the richness?

 

PM Rabbid, he will be able to answer any questions you have about the vortech.

 

Your going to have to scale the 440 injectors with the R4 .No if and buts about it . You can get a flash for the 440's [ I flashed for my 550's ] And tuned it with the R4 . I think that is the best way to go . Even if you put on the smaller pulley , you will still need to scale the injectors and tune it . It will still run rich untill you scale the injectors

 

who did the flash......?

 

Technosquare or AAM can do the flash. I just sent my ECU to get flashed for 550's.

 

I got the TS flash already so I guess I'll save few $

 

scaling the injectors is not part of the flash. you have to specifically ask them to scale the injectors. If you already have the limited flash they only charge like $300 to scale the injectors.

 

I called TS and it will cost $150 to reflash for the injectors
