anyone?

Pulling timing, no problem.
Deleting the rear O2s, no problem.

Now, that cam will require a custom tune no matter what.
Even if by some chance the car will start and run, it will need help via tuning.
Your best bet is to contact a CMR dealer that can make you a custom tune that can be loaded into your Predator and tweaked on the dyno.

ok so when I have this custom tune made can I have them retard the timing or do I have to do it?

Yea get a tune,

In the mean time, you can up the rev limiter to 6800 or whatever for your cam.

Set your injector slope to -25 or -30 and increase your Power enrichment to positive 27 or +30 somethin

You can pull timing (spark) when u go to the track to spray, pull 8 to 10 percent if your on a 150 shot

Also wait till you throw you codes, then tune them out

Get a timing tuner to pull timing when you spray, like from harrisspeedworks or the likes.

That way u don't compromise your na tune for the spray
