Well ive just about had it with catalytic converters and how they rattle..i just got a magnaflow converter and it rattles after like 6 months....is this normal? can it be taken back on warrentee? or should i say screw it and take it out and run a simulator? Is there any simulator that isnt going to die in no time? any help would be awsome..phil
Simulators in general dont work... hpt gets rid of that code wonderfully though

ic ic...well come to the mainland hehe..im going to see if i can get it under warenteee first if not well....dunno..not like my car needs to be louder!..phil
Actually the only sim that I know of that will work every time is a manual O2 sim. Cost about $5. If you do a search for manual O2 sim or $5 O2 sim there is a few post on it. there is other O2 sims and they do work, but many people have had issues with them. HPT is always a good option (more so if you plan to do other performance stuff).

Yeah, before I had HPT i didnt run anything, and rarely got the cat ineffecient code.... P0300 was my friend, damn forged pistons.
