It still makes power at full throttle past 5000 rpm, just the 91 octane and 90 deg weather at dead sea level didn't work with the generic tune (not knocking Haibeck at all- pun intended), but nobody can possibly tune for all elevations and fuel blends across the country. The off-the-shelf tune did work well in Phoenix (1100 ft elevation) in 90 deg spring time temps- go figure- I think the LT5 is Kpa/ map sensitive, especially since 92 octane was the norm 20 years ago.

Mike, thank you also for sharing your knowledge!
I should say that to be honest, when you and Dom start speaking in "tongues" ( read that as ECM speak! ) I struggle to understand most of what you are saying. I left cars & went to boats in the late 70's just about the time electronic carbs came in so to say that I'm behind the curve is not accurate....it's more like I can't even see the curve from where I'm standing.
