my centurion is 400 h past TBO still strong engine, but time for OH is near. Currently there is IO-520L. Running LOP - it is slow especially with my radar pod. I love the ability to go above the weather and fast, but my primary flying is within 200 NM range. Should I put IO-550 in it (with new prop) or TNIO-520 with new prop? If you have personal experience please share.
Thanks
