what plugs you guys running with the sct tuner. im running ngk and pinging with 91 tune with 93 gas. and its really bad wth 93/93
i htink i need new plugs ? should i just run stock champs or stage colder and see how that does ?

 

im running e3's with mine but i would probally go with the stock copper ones what degree t-stat are u running?

 

plenum isdone and running 180 t-stat

 

Running NGk v powers.

I think you have a problem but not necessarily an SCT or plug issue.

How long has it been pinging? Is it possible you got some bad gas? I had an issue once with pinging that come to find out the gas coming out of the pump was marked as 93 but was really 89.

 

I got the 3923's or whatever they are

 

I am running the 93 tune with 91 gas, and the only time it pings is under load in O/D at highway speeds.

I have ran 3923s and currently NGK V-powers, no noticeable difference in pinging/power.

Where do you get your gas? Certain stations are to be avoided. Example... I find Shell, Mobil, and Cenex gasoline around here have little to no ping in the above scenario. In the same scenario with gas from BP, the truck pings more. Avoid Casey's General Store, if you have them, like the plague.

 

I use the accel U groove plugs that come with the Accel tune up kit. No pinging.

I thought i had pinging, but it was just some loose header bolts.

Truck runs GREAT.

 

3923's here too.. never had a pinging issue

 

Im running the stock heat range, autolites which are 3924's, when I do a tuneup I will probrably go to the 3923's
Never had a ping yet

 

so i guess i should try the autolites 3923 1st before the stock champs RC12LC4 see how that does.


been running 93 gas for the last 3 months since i got the tuner , been using BP gas
