noob tire question
 

When I ordered my phoenix chip I was running 265/75r16. Before the chip arrived I needed new shoes and caught a deal on some 285/75r16. The chip was burned and I didn't think much of it, but the shifting seems a little off. Almost jumpy and at part throttle on any tune the second to third shift is the most noticeable. Do I need to get reburned or look somewhere else for the issue?

I think we got this handled with email.
