I don't know if everyone has seen this. First time I have. Lots like a simple way to read a/f. Comes with a o2 sensor..good reason to keep the stock exhaust

not worth it, we have EFI and you need to datalog TPS and RPM also for it to mean anything

the only thing i would consider is the WBC for the purpose of using it as a nitrous controller too

i guess i should have included this along with that link also....

it dosn't have a TPS but it might give enough information to get a good estimate on tuning with a fimak w/o goin to a dyno...then again goin to a dyno would probably be less expensive, unless you buy parts one at a time.
