just got my celica dyno-ed.
hp at 153
tq at 173
the problem is the the horse power stops at about 5500 rpm. my air\fuel ratio becomes too rich after 5300 rpm.

what should i do. the dyno guy told me to buy an Apex-i S-AFC.

whould that solve my problem or is there a cheaper solution.


about my car:
89 celica with 96 3sgte
ported head and balanced block
not much else

Good.... ;)

That was my main problem on my 3sgte... venting to the atmosphere. :(

You could try messing with the AFM, but it won't give you ideal tuning, you'll still be rich sometimes and lean others. An air/fuel controller is your best bet aside from standalone or maybe a Megasquirt, but you'd have to do your own research on that.
