Down pipe and muffler delete, tune?

Brokencrack · 03-29-2015, 09:36 AM

Hey all.
I just bought a 2008 135 that came with a Dinan stage 2. Now I'm wanting to do DP's and maybe a muffler delete.
Will I need a tuner to help that out?
What brand would you go with?

I don't have to pass emission tests of any kind.

You don't NEED a tune, but it will help yes. I'm FBO with no tune to speak of yet. Going to get a COBB AP and run Stage 2+ daily.

I would suggest a jb4. In a little bias though. The first mods I bought were an intake muffler delete and the jb4. Installed them all at once. The jb4 keeps growing with you as you mod more so no need to buy more maps. It also comes with loads of other features. Meth integration is easy as well, if you ever plan to go that way. A lot of people use Cobb. I've seen A lot of signatures with that in it. I use all the other features and the jb4 mobile app and I really like it. Read up on all the options and see which fits you better. For me it was BMS.

I had a COBB just installed JB4. Hanging up your computer is by far the best mod you can purchase. JB4s learning map is great, I have DPs and full catless exhaust, installing my I yet cooler this week and hoping to go e85, not having to get retuned with every upgrades a plus!

Without a tune that has DP specific maps, you will not be getting full advantage of the DP.
You also will be getting an engine light.

I would go with a JB4, being the most proven tune for our platform
