Hey guys I just installed my Motordyne Tdx v2 and the ART pipes in my 2008 350z. I had a couple of questions about throttle response and start up. After I was done with the install I took it for a test drive to hear how it sounded (Amazing by the way, I recommend this system 100%). First thing I realized was that in the 1-3k rpm range it felt really unresponsive and different then when the stock system. I'm thinking a Tune is needed? Also, on start up (Cold or Warmed up) it almost dies and then goes back to idling fine. Any Suggestions?

Also, I'm getting a tune sometime within the next month.

Thanks

Probably running lean.

 

Reset ecu and do the idle and throttle procedure

 

+1 ^

ecu reset will help. but you will still be running lean and a tune will be best to squeeze every hp out of it. congrats on the awesome exhaust setup!

 

Alright thanks guys! I will definitely be getting a tune soon.

And thanks Bmurray I love the Motordyne so far, its everything I was looking for and more. Its a really quality setup.

 

A tune should fix things up - Get one if you don't plan on switching out or adding mods anytime soon (to save on the cost of a retune).

what intakes are you running. after i installed mine i was lean and hit 275 whp, after the tune i hit 286. let us know how you like it after the tune!

 

I'm stock for intake, deciding if I want to stay stock or get something else. Not sure yet. I am going to wait until I get my 4.08 gears to get it tuned because I don't want to have to get a re tune just to fix the speedo. Ill post my results when it gets tuned. Should be within the next month or so.
