i just got done with a 305 tbi to a 350 tbi swap. used the same tbi, even the injectors, i thought that would make me a little lean. but i am runing rich. you can smell fuel from the exhaust. i have the same chip and everything from my 305. any ideas?

 

...

 

Fuel rate is controlled largely by RPM, coolant temperature, throttle position, and MAP. With the fuel pressure being equal, if one of those is askew, the fuel rate will be off as well.

 

is there any way to lean out a tbi?

 

sure prom tuning...
