^Yeah I'd say so.
Did you ask for a "high number" tune? Because that graph looks like it. Haven't seen a lot of 20g-XTR graphs so maybe I'm wrong.. but I'd assume you could get a flatter torque curve. |

Congrats OP! And great job Dan!! 11 sec street car making peak torque under 4k.

I think the torque drop is an illusion due to the RPM's on the chart being so close together. Horsepower doesn't start to drop until 6500rpm which tells me the torque is fairly flat. Perhaps the high peak torque is due to an initial boost spike? |

I wasn't refering to the correction factor or the number's being 'high'. Just that the graph shows high peak numbers vs a tune with less peak power but more usable power.
Maybe it's just how the turbo performs, I don't know. I'd like to see the boost plot. |

Thanks! Keeping the peak tq low was a goal, along with maintaining good throttle response. This is my DD, so wanted to keep it drive-able with a fairly wide power band. Dan & Matt @ Mach V were very helpful in guiding me along and making final "adjustments".

Nice setup man. i just got tuned with a 20gxt by dan and also had almost identical numbers as you.
i bet its fun.! |

Congrats on the power, nice chunk over stock! What inlet size and hotside does that XTR have?

Nice setup OP. Looks like stock spool until 3500rpm and then it just takes off! Great street setup IMO. This thing would wail on e85. |

8cm is the hot side. The inlet is either stock (2.4") or 3". I think turbo is usually a 2.4" inlet. |

I'm no subbie guy, but sense when does peak tq at 3750 equate to a "high numbers tune"? Tq curve looks pretty grunty to me. I'm sure it drives like a beast of a DD.
