Desmond, NOT having a go at you or anything - obviously you've had a lot more experience with this than I have, but I still cannot agree that VTEC at such low RPM is a good thing. There is always an exception to the rule, but from MY experience the VTEC point is very well optimised from factory. +/- Fuel Maps can be altered to get some big gains, but to be completely honest, the VTEC point stays the same.

do you have any dyno charts of your tuning before and after ??? would be interesting thing to add to this discussion.

As for the B18C with VTEC at 6300-6500ish (tacho may be out a bit..) it IS making very good power the whole RPM range but the VTEC is VERY strong. and pulls right to and through 9000RPM..
