Made such a huge difference I wish I would have done it sooner. 1st thru 3rd pulls so much harder and the throttle chop is completely gone now.

Exactly what I needed

It did everything I needed from the ECU tune. Deadspot at 6-7k fixed..check, pulls way better from the get go and they all the gears ..check, revs to 9500 check and fun factor increased 10 fold checkkkkkkk. Met my every expectation.
