Re:turbo gsr and still slow need help
 
Your problem is right here...

---------
vtec afc
missing link
rc550cc injectors
---------

Are you using your VAFC to scale your injectors? If so, get rid of that missing link. I can explain the huge long scenerio of why you shouldn't have it, (if you want, let me know), but the moral of the story is, if you're using your VAFC to scale your injectors, it MUST see boost, and your missing link it not allowing that.

Second.. you're running 550cc injectors which require a -56% cut + latency compensation. You need to start at your settings are something like -48% or so, and build from there.. probably to about -43%, or -42%...

If this is not what you're trying to accomplish, let me know...

..but for now, PLEASE remove that missing link. YOu're going to damage your engine trying to boost with that and the VAFC scaling your injectors.
