i thought HKS SC kits dont respond to any other mods? and you needed to be stock in order to have it?

well this one did, like i said in my first post, but it also made it about a half-point leaner. i think its still safe. it reaches~ 11.3 now whereas before, it was ~10.8. i just added the 1/4" spacer to see what it would do. didn't tune it, but i think i'm still safe afr-wise.
sorry about the poor photo quality.

not only that, but the two extra injectors that come with the hks kit take up A LOT of space in the plenum also.

Is there any reason why this dyno run didn't go to 6500. Why the drop before redline?

Looks like you would have gained more but you cut the dyno short. 11.3 A/F is still very safe...

i noticed that after the pulls. i think when he saw the shift light blink, he ended the pull. the shop i used doesn't see many z/g cars.

Hey Matt, good nums. Have an appt on the 13th @ XS...Hopefully, we'll see good nums. I did the 5/16" spacer, and the car is symptomatic to running a little on the rich side...( BUTT DYNO ONLY). Can't wait, will let you all know how it goes.

symptomatic how? if anything, you should be leaner with the spacer. what i've noticed since adding mine is that its a bit leaner, and the engine temp has gone up a bit higher than that with just the sc. my oem needle is a bit below the midpoint. where's yours?
