My stock tune has negative values in the low pedal position MAP A, B and C tables. However, my current version of HPTuners forces them to zero. My version is 2.24.734.
Is this going to be a problem when if I flash it again?

Never tried it but I really don't think it will hurt anything. You cant get negative power from the engine anyway.
Sure you can ... think engine braking.
Issue ..? There's only one way to find out.
I have noticed in logging pedal position and TPS that they most of the time correlate, not matched though, but a lot of the time at part throttle (think cruising down the highway and climbing a hill applying enough throttle to maintain) the TPS will read 100% while the pedal will only read 40-60. I think the worse that would happen is you would feel less engine breaking, but I don't think it would be an issue per say.

I was able to save the negative values by loading an older tune and manually changing the higher load cells rather than making compare values "zero". No harm, no foul. The negative values were generally in cells that would never be hit anyways, but I didn't want to chance it.

Limits have been updated recently to allow negative values. Download the latest 2.24 version and try again. If you still can't enter negative values, e-mail support and include your OSID.
Yea, it seems like there are a few weird things happening to "older" calibrations with the newer versions of 2.24 that I need to email support about. For example, 2002 jbodies do NOT have a knock retard PID available anymore lol.
