1.)Bone stock 93 octane -1800 DA 0 slope
Trap 127mph x3 runs dead consistent
2.)Intake / 200 cell Catted DP's93 octane -1800 DA 0 slope , 128mph trap x3 runs dead consistent
3.)Intake / DP's BMS set to 3 psi new firmware + 1800 DA 93 octane
Trap 129mph x3 runs dead consistent
4.) BMS set to +3.5 psi 93 octane + 2000 DA
Trap 130mph x 3 runs dead consistent
5.) BMS set to +4 psi 93 octane, + 1700 DA ,
Trap speed 129.5 , 128 , 127
Rapid heat soak and def less pull above 6 rpm .
Bottom line is a car that makes a true 680whp with a DCT should trap 135mph all day long and if someone does no one will dispute that . Dynos have been so manipulated by some shops that I'm actually to the point of totally discounting absolute numbers and only look at deltas from mods and the shape of the power curve .

1. Stock???? 127mph?
Then #3. add cold air intake and catted DP and BMS and only gain 2mph??
confused... I thought we were like 121,122 stock???
