Anyone try BKP piggy back(i think from germany).
Just uninstall my JB4(on map 3) yesterday,the feel is almost or better than my JB4 map 3 methanol.
My last dyno full bolt ons with JB4 map3 peak 370bhp@5,393rpm 572nm@3,898rpm.Map 0 is 279.3bhp@4816rpm 445.4nm@3218rpm.
Dont feel right because i thought stock should be 306bhp?And after 5,400 rpm my power drop but this BKP still pulling till 7,000rpm+/-.
Just wanna confirm the limit of JB4,anyway BKP offer 7 days money back.i will need to dyno again to prove the graph is more flat compare with JB4 which go down hill after my peak.

I guess you got whp numbers at the dyno, not bhp! 280whp looks about right for a FBO 335i with stock boost. 370whp with meth however is rather low.

Seems they just resell the CP-E standback

Never heard of it but I know most of the piggybacks JB3 and JB4 included are also private labeled out in parts of the world. Post photos and we can tell you which one it is.

On the JB4 map 3 it can make as much or as little power as you want. It all depends on how much boost you've set it for and how much methanol flow you have. Also for higher boost levels you would want to do the 15ohm mod to unlock an extra 1-2psi.
