2015 ecoboost perfomance drop manual

[Bikeman315]

Well when you tell the op to put the OEM plugs back in, which have been proven to contribute to LSPI on these engines, then yes this thread will get longer.

OP don't put your OEM plugs back in please, check the 6510's and make sure they are gapped correctly and the tip isn't damaged.

I did not say put the OEM plugs back, just the ones he took out. They may or may not be OEM. The OP didn’t tell us nor did he mention the condition they were in. I agree that the 6510’s should be fine if gapped properly. At this point we do not even know if he had a problem but unfortunately he does now.

Guys your asking the OP to chase his tail. We do not even know if his 0-60 time was right since he was using the on board computer. All of the advise given is solid, especially about boost leaks. That said having a guy change plugs without knowing anything about his car is going to lead him down a dark hole. The overboost light is prove of that. IMHO he should put the original plugs back in, check for the light, and bring the car in to be checked. Hopefully he did a full maintenance on the car before doing WOT 0-60 blasts. If not, I'm afraid this post is going to get a lot longer.

I didn't realize he was still under warranty. That's where I would start. Take it the dealer and have them scan it, check the fluids and etc. My advice was more geared towards what you would do without a warranty on a used car.

It could be your shift points. Once the engine hits 4500 rpm, the help from the turbo down. Try shifting when you get to 4500 rpm instead of near redline.
