I have been running a tekin rs pro in my b4, but it got moved to the b44. I should be getting a speed passion reventon r to go into my b4 any day now. Everyone has told me how not smooth the tekin is & how smooth the speed passion is, so I'm giving it a try. What I have found is the tekin is very smooth until you add boost, then it's like a light switch. Between putting the rs pro in the b44 & getting the reventon in I have been borrowing my sons mmp. I HATE IT! I'm getting less punch (I can't wheelie down the front straight & have a harder time clearing a double right after a hairpin), it's not as smooth, I get less run time, the sensor forgets where it is every now & then, & I had to put a glitch buster in.
