what are you guys having programmed into your trucks for a 2# or 4# pulley?

Stock these motors shift at 5200 as I understand it, and most of the chip tuners seem to want to increase this to 5400. I assume this is to have the 2nd gear starting point higher into the power band. To me, it seems the motor falls flat in that last couple of hundred, but it could just be me. Where is the stock rev limiter set at? 5500? And where do custom chip folks generally put their rev limiter at with the chip? The shift duration for 1-2 shifts is 400ms (500ms being half a second) of 4 cylinder operation. It seems most are simply changing that duration to 200ms (2/10's of a second) but not actually removing the 4 cyl operation nor are they increasing line pressure using the chip.

Thanks in advance for any information on how you have (or would set up) your chip for a daily driver...

Mine with 4# pulley, is shifting out at 5400, and sometimes just a tad later. It never falls flat. Rev limit is set at 6000.

Shift duration overall is decreased. Unsure of the values of them. if its dropped to 4 cly on shift i sure cna't feel it =)
