550cc and lexus afm

supradrift · 06-28-2007, 06:30 PM

I have done alot of searching and couldn't find exactly what i was looking for. i plan on changing my injectors to 550cc and using the lexus afm becuase alot of people on here recommend doing so.

My question is that if i do that will there be need for tuning or will the car be fine since the afm is ment for the 550's.

If your car is actually tuned and the AFR isn't being monitored and adjusted for by the ECU any more then: YES, get it tuned.

get real , you'll have to tune it .
it would be good to get baseline figures on your car now before you start mods.
the air fuel mixture will be close after the change but i wouldn't plan on not to have touch anything after you change the fuel inhectors and air flow meter
