Bnr thanks

[2013sonicblk rs]

i sent in my logs and in about a week bnr sent me my retune and i have to say what a big improvment it is so my more crisp and smooth they lowered my shift points a little but it is still running out of power before it makes it to its next shift point on the top 2 gears 5th abd 6th bnr is it possible to set all gears to shift at 5200 rpms. when it runs out of power i put it in manual and it surges forward and 5200 seems like its the sweet point. when i send in my new logs can and would u set all shift points to 5200 rpms if i requested it

thx bnr keep up the good work

You should consider removing the tumblers in the intake manifold, it will give you some more power above 5,000 rpm and allow you to hold gears longer.
