Where do you see your gains? Low end? Top end?

Gains are reported to be in the mid- to high-end of the spectrum. I still have to install it to see for myself.

wait wait wait.

people with the 1zz tb were getting cel's? i never got one. i did get some oscilation but only in temperatures below freezing.

could u swap the chips from the yaris 1nz to a scion tc tb? because i noticed a greater gain in power and response using the tc TB except i got thee CEL from it.

Whooppee - you just got lucky. The rest of us had major CELs issues. Mine came on no matter what I did.

The gains seen with mine was major pickup mid to high end. The car really jumped @ 40 mph and continued excelerating from that point on, much stronger than stock.

Drilling out these rivets is a pain, but I'm working on it. I see you also used a allen key bolt so you keep the bolthead size to a minimum. There's one spot of the six that is super close fitting for an 'other than rivet' attachment.

i'd rather b lucky than good.

im thinking about taking apart my tc throttle body. it sounds like something is loose inside of it. could something b broken inside of it? the 1nz throttle body sounds solid when u shake it, no noises or feelings of movement from the inside

Well, I'll see if I have any CELs when I receive my TB next week. Won't bother with the chip swap at first and see what happens.

Okay. I just performed this excellent DIY with my 2 TBs. Everything looks, feels and sounds awesome. I'll report back if I get a CEL or not. This is an excellent mod for the money.
