1) The dyno puts no where near the load a full on drag slick launch would
2) From my understanding, Ashton only got 3 runs. 1st bogged hard. 2nd launched hard. 3rd, broke (supposed) oil pump
Don't forget to put the 333cc injs back in when you tune the car with the Nismotronic board. Also please get a 3in 95-99 Maxima MAF. The VE will thank you for it.
