500 efi not making top end power

Well that's been the unspoken standard at the OEM level forever. The OEM's have been trying to thwart tuning forever.
But with you saying that, is it hearsay or have you seen something in print from Mercruiser?
Are you having troubles with O2 sensors surviving in an OEM catalyst situation?

I’m just going to keep this as the shortest post so far I feel. If I had Smitty tune it and I had issues, I’d reach out to him and resolve the issue as he’s a very sought after tuner and customer service is second to none before I blew his name out as working on it then looking for internet ideas. Just a thought.
