First off, you have to remember that I installed this system with a set of Berk high flow cats, so my setup is most likely different from yours and most others in here. I've also done a lot of other bolt-ons in the past few months. With that being said, I had a rough idle and some cat rasp right after install. Both of those have subsided over the past 300+ miles I've put on the car. The idle is now a nice low even rumble. It sounds very V8ish. Under WOT it still screams, but in my opinion, it sounds damn close to a GT track car (it's awesome!). During normal driving it's still noticeable, but not as loud as it was immediately after install. It's either broken in, or I'm just going deaf. Or maybe a combination of both! Now I just need to get a tune.

Tuning will wake it up again; you will probably gain an additional 20whp (+ or - a tad) and will be felt in the seat of your pants when acceleration-thus making the exhaust talk more.
Unsure about the need of the sprint booster w/tune...as the acceleration rate can be changed by either UpRev or Ecutek.

I've been thinking the same about the booster. I plan to turn it off while they tune the car. If it does nothing after the tune, I'll more then likely remove it and post it for sale on here and ebay.

I'm currently tuning with Seb, and it pains me that this car (Nismo) doesn't perform as such from the factory. I felt the same about my G37 after going through the same mods and process. The car is so responsive, quick, and a tad scary! I love it!!

I'm going to a master tuner in one week for Ecutek dyno tuning. I can't wait to see the results.
