There’s no 7th injector like the supercharged 3.4s got (also terrible). The ecu “adjusts” for the boost made by the supercharger and its “amazing” is what people on mud are going to say. I’ve been there, done that, and found it to be super underwhelming and not worth 4k. The blower just made the engine bay hot, pulled timing all summer, cost me a lot of money for 91, and marginally made 2,000 -3,000 rpm better. Haltec makes a harness for their 2500, you’ll have to get a little smart and figure out which inputs the the trans needs to shift from the stock ecu, but everything else can be controlled by the haltec. Idk why people seem to be so happy with the stock ecu struggling to stop the motor from eating itself what do I know… im just a dude on the internet.It stinks of running rich. It's supercharged, and I couldn't find a 7th injector anywhere. Maybe I don't know where to look.
I've read that these engines, with the factory supercharger, are prone to detonation, so it seems logical to have added more more fuel, either with more injection capacity or a tune.
It wasn't. It's the Magnusson/TRD, added by the PO 20kmi ago. If they were sold through Toyota, they're factory, as far as I'm concerned.You sure it was born with the S/C?
Is there a VIN designation to prove so? I wouldn't know what that would be.
Heard of factory S/C 1FZ's, but never seen one. It's mythical frankly.
Sorry you had a bad experience. Mine's magnificent. It just makes stinky exhaust.There’s no 7th injector like the supercharged 3.4s got (also terrible).

Exactly.I haven't heard that running rich is a common supercharger thing, seems like most folks are concerned about getting ENOUGH fuel in there, not too much.
