Gintani official review ECU TUNE for (N63TU)

ALL: I would like to start of by saying that Gintani is the ****! The customer service from Alex and his team were amazing! I would call 4X a day and they would pick up and answer all questions lol. I was the annoying dude that would overthink and over analyze and call to ask.

I would like to say for the Record I am not knocking JB because their tunes for the money are Great!!.. Im just saying this is So much Better!! Overall!

2014 550Xi- (Full catless exhaust + K&N Filters)

GIntani Stage 1 Tune with Speed limiter Removed: (N63TU)-550XI
Official review:
1- The cold start is smooth (no bouncing revs)
2- The car idols Perfectly! soo smooth!
3- Local driving is amazing. Huge improvement of BMS JB tune. The car drives like factory but on steroids. Very smooth and effortless. No random over revving or under revving on hills or local driving.

5- The car is an Absolute Animal! It pulls like a freight train all the way to redline. The HP/Torque can be felt on your body all the way to redline. The power does not die like in the JB it gets stronger! I would shift at 5.3K with the JB because anything after was just noise and NO POWER. The Gintani tune is POWER ALL THE WAY TO THE TOP! and the shifts are BRUTAL! even after 100mph+ it feels like a 40mph pull!

6-I had my Vbox Connected to my car to document some runs and here they are in comparison to JB tune.

0-60 (3.7-3.8)
40-100 (6.3-6.6)
60-130 (10.3-10.8) I would average about 10.5.

0-60 (3.6) Consistently 10X in a row!. With better tires I can do 3.4
40-100 (5.2-5.7) I was trying different shifting methods. shifting after 6K provides best results.
60-130 (9.9) I was only able to do One pull and it was UPHILL HIGHWAY! ahaha Easily Mid to high 9s

I could not believe how much better the car drives and the POWER!! its a never ending ride on a freight train!

A real tune that is Safe and provides Power and enhanced drivability .. This is it!!
FOR THE RECORD: This is is Honest review. I paid for the tune and did not receive any special treatment or anything. I just wanted a faster car. I currently hold the 1/4 Record and am looking to go even faster!
