I've just fitted a Blitz SBC i-D 3 to my Chaser (the actuator line was a bitch to get to, but thats another story...) and couldnt resist the urge to tweak with the boost. I've pushed her up to 1 bar and the mid-range pull is good enough for me to be grinning like an idiot after a quick thrap.
The question i have (since i've taken out the PFC until i get her tuned) is that do the 1jz's have an air-flow cut? It seemed that in higher gears (3rd and 4th) that it started to break up almost like it was missfiring. I haven't gapped the plugs to anything different to the factory, so maybe it is misfiring, but i was wondering what the AFM's are good up until on the 1jz's? Oh and BTW it was a very cool night last night when i was testing, around 5 degrees or so.
