Anyone ever had any trouble with a 22re leaning out when you go full throttle, even though I turned the afm up 10 clicks and up the fuel pressure 10psi, somehow my wideband shows it’s still going extremely lean, tried a second afm, same result. It’s a mild stroker build, wondering if I need up go up to and aftermarket injector?

 

How lean do you mean? Do you know your injectors are flowing well? I had mine cleaned and there was a significant difference in flow, according to the test results.

 

Afr 16.0- 17.0, injectors are brand new from Osidtiger, tried old stock ones as well, same result

 

Hmm, yeah, that is lean. What about at steady state cruise? I don’t have any datapoints to compare in my 22re but do run a wideband in my 327.

 

Cruise and idle it’s fine , holds 14.7, soon as I roll on the throttle it will do lean and never recover, even tried another tps and adjusted according to spec, still no good. I’ve seen people run stock computers on much more heavily modified engines, almost thinking about trying a second ecu
