I'm trying to tune a 02 Rsx type S, Peakboost t3/t4, 1000cc ID injectors, 255lph and stock return less fuel rail.

AS soon as vtec (6000) comes on and pass 6800, it goes scary lean, 16ar 17ar.

I included the map and two logs. The map is rough and needs more tuning but at WOT pass vtec its maxed.

I don’t know if it has to do with fuel trim or something. Any help or insight would be greatly appreciated.

Check the fuel pressure to see what it is doing. It sounds like you have very little pressure.
