Pinging with Cobb tune?

[Ibuildnoleaks]

Just installed the Stage 1 91 performance tune on my 17, noticed some pinging under light/mid throttle. Anyone else have anything like this happen? Should I be worried? Just picked up some SP-542 plugs and plan on changing tonight.

How many miles on your plugs?

Cobb tunes can be picky with gas. Could be a bad batch of gas. Try a different gas station/brand.

28,000ish on plugs. Changing them tonight.

I haven’t have any issues with Cobb or stage 2 @goosetuned. Other than many smiles!!

Ok, changed plugs and gas. It actually runs better than ever! Very smooth pulls. How much boost are you guys seeing out of stage 1 91 octane tune? My display showed 24.98 which seems pretty high to me.

I think you solved by changing the plugs. We're they the originals? What plug did you replace with? It seems most tunes require a different spark plug due to the tune.

I’m also about to change my plugs. I believe mine are original - what is the best plug to switch to?!?? I’m going to be pretty heavily modding mine - soon. Tune. Exhaust. DPipes. Intake. Turbo adapters... etc, etc,.... NEED THE BEST SPARK!!

Stick with motorcraft plugs. SP-542 will work best in your situation. They are no longer sold individually but instead in a kit by Ford Performance. They come pregapped around 0.031 which works in most cases but gapping down to .028 would be best.

Also check with your tuner since most have their own preferences.

The sp-542 hype is real. Just installed a set gapped at .28
Feels good
