Diablo tune on an '01 GT

torrid69 · Apr 28, 2006

I currently have the Diablo Predator tune installed in my basically stock '01 GT, which has a K&N, 3.73s and 2-chamber flows. I do feel a difference with the factory tune from the Diablo, and I've ran 13.77 @102.1 mph. But now i would like to start squeezing some more hp from the Diablo by toying with the spark and fuel options. Anybody else done this yet?

we have covered this alot do a search and there will be alot of threads on this.

but for my input most people that have it max out the timing but if it starts to ping then they back out of it a few degrees. Personally it would be best to do it on a dyno to get a A/F ratio reading also

i was getting pinging at the track and backed the timing by 4 degrees, it helped by i still noticed some slight pinging. thanks for the info.

Then you're about as good as it will get until.... you get on a dyno and see what your a/f ratio is and add/subtract fuel from there and re-run on the same dyno within a few hours or less.

If you have an auto, you can firm up the shifts or track test different shift points.

Yeah you should do some research. There are alot of threads about this. You will see alot of guys max out the timing. I did and have no ping. But I have not messed with the air/fuel.

They consider that proprietary information. You won't find out what they change to make the Predator Tune.
