Default Bad FPR

Well finally my FPR is crapping out on me, 2-stroke wont calm it down anymore and it make that real loud "clack clack clack" noise when i let off the throttle.

Is there any tips or hints on replacing it, ive tried lookin in the factory service manual for anything about it and found nothing so far. it just takes me around in circles on how to remove the cp3

Just To Get A Read On Any Prior Issues - Or Any Leads Of Interest..

Reason I Ask - I Hate Trusting My Stealer With Warranty Work On My Trucks But If I Give Them A Good Stumper They Actually Look Into It.. Or If They Know From Prior Issues The May Share The Wealth.

modified b1010 on efi to help it out, you could also replace it with a stock one, or buy a modded one for the same price.

I eventually replaced mine with a modded one and tuned it with efi live, now it purrs at idle sitting at about 5000-5300psi.
