Currently at 283 at the wheels on 23 psi. I replaced the plugs with br7es and things were great for about 2k miles now they gotta be swapped again.it gets laggy and falls on it's face in higher rpm's usually passed 5500 rpm's . I'm goin with bpr7es and lowering the gap a bit. Any other recommendations or suggestions ?

 

what gap are you running? maybe fuel cut?

 

What was the problems with the plugs 2000 miles ago---if nothing go back to them--even if they are iridium and cost more as I am sure they do--- you may also want to know the difference between the br7es and bpr7es---they are not the same.

 

Gap at 0.020", make sure your wires arent junk, and make sure the sparkplugs are tight. I have also seen water build up in the sparkplug tubes from people being a little too generous with the water when washing the car. If you have random CEL, things like the exhaust cam sensor can cause issues as well.

 

Same thing with the last plugs and I know the bpr has a protruding tip. Plugs just don't last long. I gapped em at .025 I was told to try .022 since it's at 23 psi

 

Im running the BR7es gapped @ .025 with no problem here. what do you mean by falling on it's face. like hitting a brick wall or just bogging?

 

It just loses a lot of power picks it back up then loses it again. Enough to where it's extremely noticeable. When I change plugs it fixes it for about 2 to 3000 miles.

 

Sounds like you are running too rich and fouling out the plugs quickly.

 

^^ This, sounds like a too rich tune. what is your AFR's at WOT?

 

Not sure but I changed gas stations and problems gone. U would think the trusted local owned has station would be the perfect one but nope I'll keep u updated haven't had it long so I haven't put an afr gauge in it yet.

 

bad gas. that might do it. you should invest in a afr gauge, its well worth it. btw, http://www.toptiergas.com/retailers.html , i only pump at these stations listed.

 

It was a local owned shell station that Exxon recently bought out but kept the local owners which are really trusted people. Not blaming them but switching fixed it Atleast for now. I went to bp which marathon bought here and it was like magic
