Ignition setup w/N20???

[Blaster]

I bought a nitrous works 125hp wet plate for my 1991 GT, it's stroked to a 331 w/heads etc. Anyhow, I bought a MSD digital 6 plus for the car but what do I do about the factory rev limiter??? It's a stick car and I power shift it so it hits the factory limiter in 1st gear often (I have 4.10's) and I don't want to scatter parts after I put the nitrous on it. I also have a custom chip burned for it. Do I set my MSD to cut the power at say 6200rpm before the factory limiter cuts the fuel at 6250rpm, or do I get my tuner to set the factory rpm with a new chip to say 7000rpm and get my MSD to cut it at say 6300rpm??? I'm scared of hitting the rev limiter with juice on and I need a cheap/simple solution for not grenading my engine while power shifting. Help.

The guys will chime in here soon on this, but I thought the factory rev limiter was in the distributor?

Have your tuner re-burn your chip with the rev limiter set to well above your intended limit (7000 like you say). Then use the soft rev limiter of the MSD to control.

Rev limiters are NEVER a good idea on the snow. I HIGHLY recommend what Jeff said, and I'd also throw a window switch on her that kills the snow about 200 RPM before the soft touch rev limiter.
