I have a question on the vtec hi and vtec lo.

I have mine set at 6100 hi and 5800 lo. If I was to drop the vtec crossover point, will i need a retune? or will it adjust the map, so that i retain the same fuel settings at the cross over?

not sure if that makes sense.

 

you will need to retune the fueling. Dropping the crossover will open the valve more, earlier and cause a lean spot.

 

them apexi systems dont work all that well. IMO
