This is my slack dog tune on my FG that I have been running the last few months. I can tune further but just couldn't be bothered doing anything of late considering the car does what I want it to do.
Now I must admit I don't relentlessly hammer the thing and have not had any long WOT runs but I run it up to the detent switch on the accelerator to the rev cut regularly.
Car has nizpro intercooler/ Twin 3" manta/700cc injectors
This is all that I have done to the tune
1. Injectors scaled by me to run good fuel ratios at WOT.
2. Overboost threshold figure adjusted to prevent cutout.
Thats it
It will run 10 psi down low and build up to 15psi up higher in the rev range.
Runs stock spark maps. I can't hear any knock (yes some will say its there) but I suspect the knock sensors are doing their thing and pulling spark a little.
Even then you would only adjust one line on the borderline knock table to put the spark in a no knock retart position.
All of 5min work apart from the scalling.
Apart from adjusting the borderline knock table to more conservative numbers on the bottom load line, what else needs to be done to secure a slack dog tune.
