Power Loss Issue. Help!
 

Hi I have a 2010 with Invidia Gemini Catback, High Flow Cats, and Injen CAI intake on the car. I've noticed when I get around 4500rpm the car seems to bog down and no longer accelerates. I'm not getting any codes, no exhaust leaks, all intake piping and hoses are connected properly. When I'm in high gears and slowly accelerate I do not have any issues until around 5200rpm. I bought the car used not too long ago with the CAI and high flow cats. Has about 65k on the motor. Car runs fun through normal daily driving but when I try to let it free this issue happens. I've searched through the threads, other sites and can't find anything else. Any idea what this could be before I take it to the shop?

I'd clean the Mafs/throttle bodies and change the plugs. At least rule out general maintenance as a cause for the issue.

As per Chuck33079, I'd do a little cleaning (I got 0.05 USD that says it's dirty TBs), but would hold off on changing the plugs.

Start with the MAFs (very easy job - screwdriver, can of spray cleaner, and 10-15 minutes each). If that doesn't clear things up, do the TBs. Several DIYs on this site for both jobs.

Thank you guys for the quick response. I will try these things tonight after work. Much appreciated.
