HI I HAVE GOT A 98 TERZO 3 AND HAVE FITTED HKS BLOW OFF VALUE K&N AIR FILTER A FULL DE-CAT SYSTEM AND IT RUNS LOVELY NOW FITTED HKS IRIDIUM PLUGS AND I GET THE ODD STUTTER I HAVE FITTED FRONT MOUNTED INTERCOOLER 2DAY ITS NOW RUNNING ROUGH ON IDLE AND STUTTERING ON REVERING DO I NEED TO RESET ECU OR ANY OTHER HELP U CAN GIVE WILL BE GREATED RECEIVED THANKS

 

Probably to do with the fuelling. You will be getting far denser air so it will be needing more fuel. I am sure someone else more techincal can give you the answer of what to do next. I am sure it may need remapping though.

Cheers

When I fitted my fmic the car ran like a bag of poo. It was mainly down to the forge vta I had so I binned that and fitted an SQV, t ran better but still juddered and cut out.

What ecu are you running? because with the fmic you really need a remap.
