will i hurt 300c to drive to dyno using perf 93 oct tune?

[brute750]

Hi I have a 05 300c. Had vortec tune installed but have been having issues. Can I drive car with 93 Oct performance tune? Or should I reload vortec tune to get it around town and to Dyno. Car has vortec charger, long tubes, forged internals, cam, exhaust, etc. Trying to come up with an idea that won't blow motor. Thanks.

When trying to load vortec tune it keeps telling me predator is rejecting backup, it appears to be a predator tune. So I don't know how to even load vortec tune.

you cant use 2 tools at once, it always leads to issues....one tool is currently married to the car, and you have to restore that to stock before you can use the other tool.

if the car has a supercharger, you have no choice but to use the supercharger tune, the car will not run with the 93 tune.

thanks

Oh OK. Well I loaded the 93 Oct tune and it seems to run better than it has been. How would I get the vortec tune back in it? Since it can't find a backup?

How will I know what programmer is married to the car? I would assume its the one with the vortec tune but that one won't work.

then the regular tool is married, you need to restore that one then you can use the vortech tool...

I have to tuners. Both identical. Just the one has the vortec info on it. So I guess that's the one I'll have to restore. Is there a sequence to use to restore it?

you simply need to undo what you did inthe opposite order, one tool is married, unmarry it, then load the one with the vortech tune.
