hi guys just fitted a fmic and induction kit on my 94 sti.was just wondering will the car run ok with these mods or will i need to get ecu etc adjusted or will it adjust its self ? ?just worried about the extra air dont want it to lean out wil it ?.its runnin standard boost to.thanx guys

 

It will probably be better to get a re-map if avaliable. The only way of seeing if it is running lean is to do a rolling road session having explained very clearly what you want to find out.

 

yer ok thanx i think all should be ok tho id like to hear from some one with same set up if possible.and wats that cha cha cha noise im gettin thru air filter. ? ?

 

If you are getting the same noise as I do it will sound like a steam engine between 3000 and 4000 revs (approx). I asked about this when I had my car in for a tweak of the map and the mapper agreed with me that it was turbo surge. Hope you get it running well, might be worth putting a bottle of millars octane booster in to reduce any chance of det due to slight weak mixture.
