topend power lacking...
 

my FD feels like its down on power... I'd have to say probably 50hp or so.0-4500RPM it's got tons of power, but it just doesn't "pick up" as well above that.

The boost pattern is inconsistant as well.

sometimes I get a perfect 10-8-10... sometimes, I get 10psi - 8psi - 12psi, when it does this the car is slower. If I let off and get back on the gas at say, 5000RPM, it will properly respool at 10PSI and the car goes again.

The car seems to have a slight misfire at high RPM, veeerrry slight though. I don't think this is the issue.


Car has dual cone filters, 3" downpipe/midpipe/catback to stock muffler. Going to replace the stock muffler soon as it has a couple holes in it now. No fuel mods of any kind, going into the dealership shortly though to replace the coolant lines and fuel hoses as per the recall.

running v-power or sunoco 94 octane in the car, doubt that matters but just so I've listed everything.

IMO, if you're getting proper boost, and the engine is down on power, the "slight misfire" is likely the problem. Because of the characteristics of the rotary, what feel like a slight misfire can be one of the plugs not firing. That will cause a major power loss. I had a bad plug wire causing a misfire that I couldn't really feel, but it fell on its face at more than 1/4 throttle. Your misfire could be more RPM-related.

Therefore, check out your ignition components: plugs, wires, coils, etc., even battery voltage.

that's good advice dave.

I have a really nice new set of plug wires sitting in my garage, I should probably go ahead and put them on... maybe change my plugs too.

what plugs should I get for the FD, BUR9EQ's all around?

change the plugs and wire first. I would check the battery voltage like Dave said, but as also prementioned the coils could be shot. Stock ECU?
