*I've been having issues with my fd above 4k rpms.

The turbo's spool up fine and kick in like normal (full non-seq) until 4kish rpms and then the car just falls on its face and feels like it has no power, while the boost gauge will be reading full boost (12psi) and holds it until redline. It also seems to be making random popping sounds, no smoke that i can tell though while driving.

I just had the injectors cleaned and flow-tested and replaced my fuel filter and the spark plugs seem fine, so now i am stumped. Any info would be appreciated, my modifications are in my sig.



thanks

check your grounds, I see you have no cat if I am reading your sig correctly.

 

ive had a similar symptoms in my car before;

first time it was a ground from the firewall to the back of the intake manifold...

second time i would make full boost all the time but it would not go anywhere because my secondary throttle plattes (or whatever theyre called) were not opening all the way because of a damn vacuum line!

hope everything works out for you

 

I also have my double throttle removed, but I will check my grounds. Any other suggestions?

 

Bump, I have this exact same problem, happened yesterday too. Its annoying the hell out of me

 

So I drove my car to work the other day and it decided to run fine and it pulled hard, but then otw home it was actin up again with no power after4k Rpms. Any one have any other ideas?

 

Check your igntion system components.

 

Sounds like limp mode?

Try reseting your ECU.

 

My car went into limp mode a few times on me about 2 weeks after i got it, I was pissed it was my first rx7 and i was freaking out. It has not happened again since then but mine was doing this at about 3K rpm.

 

limp mode with the power fc?

 

2 connectors to igniter were loose....problem solved, thanks guys.
