Disableling cat codes

[M_O1500]

Is there a way to disable the codes I'm getting after deleting my cats. Or is a custom tune the only way?

you need a custom tune done... that's the only way....

Please send me an email at -- diablo DOT help AT gmail DOT com -- with the year, model, engine, tranny of your GM vehicle, any mods done to it, which diablo tool you have - the inTune i2 i2030, the inTune i3 8245 Platinum, the Trinity T1000, or the Trinity T2 EX 9245 Platinum?

and what octane gas you use, etc.. and I can send you a loooong email with info about the custom tuning, the process, etc.

Thanks!
