Your common turbo b16 setup only upgrade is 9.0:1 pistons. Stock head with Ls tranny and Victor X maifold, plus Full-Race turbo kit T360-1 .63 a.r., Hondata. On the dynapack we get a idle afr of 10.0-11.0 before completing a dyno run. If I give the car some gas before making a dyno attempt the afr idles normally around 14.0-15.0, before making a pass. Vacuum after warming up the car reads -18-20, which I suppose is good before loading the car and making a run. While trying to tune the little cam w/o vtec running it to 7500rpm the car makes 300-330whp and 224ft/lbs but for some reason the Hondata is showing that the vtec is opening up when i have turned it off using the Hondata, and it only makes 348 @ 20 psi once VTEC is engaged and turning the car to 8500rpms, Hondata shows that boost goes to 19psi by 7500 rpms and by redline boost falls to 16psi. Afr's remain 12.0-13.0 on the non-vtec and vtec dyno runs. I need help!!!
