From your sig....

predator....

4# lower pulley

Are you running the 'pulley' tune?? I've heard of this blowing up a lot of motors recently.

 

[99RedSVT]

Worth every penny.

Pinging is too much timing or too lean or too low of octane.
Any of these will destroy your motor.

Get a proper dyno tune to keep it safe.

Every time you hear a ping it is bad enough to blow a tiny chunk off the piston top. Keep your damn foot out of it and add some fuel with the predator.

PUll some timing and add some fuel with the Predator. I had to do the same thing.
Pinging will scatter your engine.

SO i should retard the timing some more?? And richen it up some..Well ill give that a try tomorrow after work and see what happens..

Don't jump on it anymore till you do.

I just added a 4# lower and put in the predator pulley tune. I heard a lot of bad stuff about the canned tunes. I retarted the timing as much as I could 10% and added about 5% on the fuel. I havent heard any pinging or detonation at WOT. It's running really rich and isnt pulling as hard as I thought it would. Waiting for my custom tune and hitting a dyno.

 

[OH-MAN]

They run real strong as they get lean right up to the part where they go boom.
Sometimes you cannot hear the pinging. Be carefull .
Check it on a dyno.

mike i have a 6lbs lower and a street tune (SCT by JDM) and am having no problems at wot in this cooler air this winter. its in your tune. you should nearly be able to run stock tune since it is so rich. i wouldnt run any of the aggressive tunes from predator. they are too aggressive in the timing. at worst, rich it up and take the timing down if you can. otherwise, go with a new tune.

also pull a plug and see how the tip looks. its the best indicator.

 

[99RedSVT]

Well i just changed teh plugs ahhh about a month ago and the front spark plug closest to the front of teh truck ont eh drivers side was prety much gone..But im gonna richen it up alot and retard the timming some more..It usta run pretty good before i dont know what happend when i dynoed it all the time the air/fuel never came above like 10 lol.

 

[Jesse@MBRP]

It sounds to me like you have the Jesse Rohr Custom Predator tune. The pulley tune with 10% more timing added to it. Don't you love that rattle? It sounds like your engine swallowed a jar of marbles??

mike are you dynoing in cold air? because you only see the detonation when it is cold. if your plugs are nearly gone, that is damn scarry. dont break this motor. the few rwhp gained isnt worth detonation.
