Custom Tune Usability Question and Major Props

[rllackey28]

First major props to the gang at PHP for the super quick turn around on my custom 87 performance tune. Sent in my HEX code on 11/14 and received an email back from Cody last night stating that it was ready to download. I couldn't have dreamed that it would be ready that quick. In fact, it was ready so quick it leads to my question.

I assumed (yes I know what they say about assuming) that it would take about 4-6 weeks to get my custom tune so I planned ahead and had the custom tune wrote for a dual system with an X-pipe and Magnapacks. But I haven't had time to put this system on yet. In fact I haven't even ordered it because I've been buying Christmas gifts for others before myself, . Right now I am running a SIDO Flowmaster 40 series. Can I run the 87 custom tune for the time being without messing something up or should I run the canned 87 tow until I can switch out the exhaust?

Thanks for the help and again all I can say is WOW for how fast the turn around was.
