Serious MAF problems

[Jeff Chambers]

With the dry shot it is going to be imperative that you have the car properly tuned. If you're running at 14:1 now and hit it with a 150 shot, you could easily roach the motor.

If I were tuning your car, I would put a four-program SCT switch chip in it with a base N/A program, then a program or two for the NOS (say a 75hp and 150hp tune). You need to find a tuner close to your area since the car needs to go on the dyno for wide band A/F measurements to do the tuning correctly. In general, I think you'll find that a switch chip will run you close to $300 and dyno time anywhere from $75 to $150 per hour. I tell EFI people to plan conservatively for two hours on the dyno for a good tune.
