can't believe no one said this yet..but hope you don't have a cheap converter...most converters without an anti balooning plate will go after a number of passes...the instant torque of nitrous at low rmp off the line causes too much stress and the converter internally explodes, throwing metal through the transmission..... ATI is the only company that even advises mild nitrous without a BP, and thats because they are $900 and up, billet, brand new converters...a B&M will be toast after 10 passes...thats your weakest spot in the driveline with No2...other than that, go fat on fuel, take a few degrees of timing out, and bump up fuel pressure a little bit...the motor will be fine with a hundred shot..good luck!!!
