Yes the numbers are without nitrous ...First dyno was with just intake and catback..Second one i added 70mm tb and camgears. If you drove it before i got it it was a LOT slower then . I was trapping at 98mph when i got it . Now i am up to 104...I have gotten about 15whp and 20tq to the wheels since i have had it . I just got the fuel pump and i also have 450's so you will see 250+whp soon. I just have to install the nitrous and fuel pump . Then off to the dyno.. Also yes i am still running stock header and cat. I got the big jump in tq from the cam gears and tuning... So yea it is a all motor dyno ....With a great tuner
