Octane vs tune

So got my car used. The only bolt on mods were flowmaster axle back and x pipe. Got a tuner after some basic stuff I did. Had just filled up with 89. Wrote Bama and asked what was available for 87. Free tunes. So why not right. Well 87 race tune tossed check engine and completely unresponsive throttle after 3500 rpm. Just sat at 2k rpm. Switch off and cleared. Ran it 25ish miles and kept popping up. Went back to the 87 performance tune. No data logs. Just goofing. I'm thinking that what I thought was stick wasn't. It's not as "zippy" now. Burned out the crap gas and am now on tank 2 of 93. Going to put a 91 performance tune on. I bet that was my stock.

Question. With as many of these cars that are out there, what's the chance of this happening. Buying cars not knowing tune and putting in lower octane gas or whatever. What's the real damage with DD driving with a little fun every now and then....

Octane vs tune

In the coyote section. Not trying to be a dick just letting you know.
Another thing that could prove effective is miles.

Pick your poison.

^ don't need any of that info for his question.

Yes running a tune that requires a higher octane and running a lower can and will cause problems.

If the car was tuned b4 it's possible you have a mix of the old tune and the new one together. That's why you switch back to stock b4 swapping to a completely different tune.

Rapinator, I'm not sure I have a "stock". I can go back to what it was to start with for me. I'll play with it this week. Back to stock. Check. Then tossing on the 91 performance. Do some data logging. Make sure it's running right. Thanks fellas.

Didn't mean you had the stock tune to swap to.
Figured you didn't as you bought the car used figured you didn't get the handheld with it.

Was giving info to what your problem possibly could have been.
