I've searched around a bit and there seem to be differing views on timing.

I will only be running a 100 wet shot MAX on my 05 GTO....I had an EFILive tune put on my car and the guy bumped up my max timing to 25-26*...

Is that too much for 100? I know several local people who are running 150 shot with 28-29* and they are saying that it will be OK.

Just looking for some more opinions...

 

Good question.....I would also like to know because i'm in the same situation.

 

every vehicle will be a little different, but you should be ok for 100 shot on the timing you have now...i cant see runnin a 150 shot on 29* of timing, i think some one may be fudgin their info a little...

 

Thats good to know. I think my timing is at 26* and i was scared to spray it with a 100 shot. I think i will probably just use the 75 jets to make sure the spray is working.....then i wont spray it until i get a tune.

 

I'm at 25* timing also. 100 shot should be fine on pump gas (93 octane)
And we all say that we're only going to spray a 100 shot max.....that's what I said too I did run it for a year like that. Now that I've stepped up to the 150 shot I just throw a little 100 octane or 110 leaded, whatever they have at the strip.
