Flow setup for 13.5 boosted

[Mark240973]

Hi,

I am after some advice on speedo set up for a 13.5t boosted touring car.
I have a Flow works competition speedo with the std firmware on it and currently run....indoors on carpet. 13.5 Gforce (black) motor on 40 actual Timing

I am having problems with getting rear traction with the car and wondered if its purely a mech set up problem or perhaps the speedo settings and punch settings are way too aggresive?

I am wondering if I should turn down the boost angle? or boost itself?

Any thoughts?

settings are 0/3/0/6/8/10/0
