REV Limiter on a 340

I have a MSD 7al box, my rev limiter seems a bit low-reads like 500rpm less. No biggie but I got some chips in the 5000 to 6000 rpm range and should have got the 6000-7000 set. Was able to find a 6800 chip on e-bay-so I guess thats 6300. Haven't hit it yet.

Its called "soft touch" but it feels like the motor runs out of gas. Car slows down quite a bit so I don't like hitting it but its there if needed. Would not drive now without it. Can relax and rev the motor a bit higher knowing it cut off if needed.
