replaced the sway bar end links up front, and last night I thought I stripped a plug hole and put the old one back in, the ceramic cracked and was shorting, so I fixed it this morning, lubed it a little and got the new one in, almost done (plugs, wires, cap and rotor have 213K miles on them)

Got EFI Live V2 and loaded my first BB tune this afternoon.

 

[vtx1800sba]

Marc how'd the BB tune turn out?

 

[gpracer1]

It runs good, trans shifts much firmer and faster, 1-2 shift is now 5250 instead of 4500 rpms.....kinda high and I just changed it to 5100 along with making TPS kickdown a little less sensitive and will reflash.

Im not sure if it is just me but it seems to idle a little smoother too.

Im going through it right now and tweaking some other settings to my liking and see how it goes. Cant wait to install my 05 efans now....even though the hottest summer on record is pretty much over

I still have that strange timing reduction at 20-30% throttle when the shift drops the rpms below 1600, the timing before the tune was down to 5 and hung for about 1.5 seconds.....now it only drops to 15 degrees then back to normal 24ish, so I dont feel it as much.

What did I do today...

Um... I transfered funds today and bought my second two door hoe!
