Dinan is big $$ for little gain. Even a JB+ piggyback has same power and costs 1/10th.
That said any tune will obviously improve performance. It's just a matter of bang for buck.
Some people might sleep better at night with the Dinan, that's fine. But there are better choices in terms of performance, and they all cost a lot less. Cobb you just remove it from the ODB port, JB4 you turn off on the steering wheel.
Show me one instance where someone had their waranty voided due to an aftermarket tune. I have yet to see a single post on that.
