JMS is easier on the warranty concerns but most people seem to have not trouble getting work done with a tune. YMMV.

From the link that fomo posted that thing would never go on my car...that is absolutely the wrong way to add boost...manipulating the signals from the pedal and tip sensor to the ecu is a dumb idea!

A properly tuned vehicle is much less likely to cause a warranty concern than the Boostmax.

I have a 2013 SHO with PP, I would hands down go with the unleashed tune, Torrie is the man. My warantee just ran out in Dec. and I had a KILLER tune in it with Meth right from 2 weeks after I owned it. You dont have to go that overboard, but you can feel VERY safe with Torrie. If I had to take it back for something, I would just return it to stock.

I am going to say +1 for torrie (Unleashed does amazing work IMO) and tunes in general. I am still under warranty and considered JMS because it can be taken off however as others here have said the JMS fakes signals and is more likely to cause an issue than a properly datalogged or dyno'd tune file.

Tune... but its up to you from a comfort standpoint... I have seen a lot of these products over the years that piggy back systems...and the one that stays around the longest is a good tune

All the dealers around my area's are tune Nazi's (Virginia)... if you even mention having a tune they wan't nothing to do with you or your factory warranty.. lol

TorrIe has taken good care of me as well


Get a tune from him.
