Message Pretty sure it is the TPS causing my issues, just want to bounce this off you guys before i order another one.

-When free revving, feels as if there is a dead spot, revs fine to 2k, stumbles and bogs from 2-3k, once it gets over 3k revs fine.

-When accelerating from stop, it is difficult to be smooth, kind of jerky and boggy, then takes off on you..

-When driving normal, acceleration rate coincides with throttle position until near WOT and then it feels like it is laboring/boggy.

-- Measured TPS:

Reference voltage(Black and Red) wires = 5.12V
Signal(Black and White) = .450 idle / 3.76 WOT
Idle switch works as should: Closed circuit with TB's closed / Open circuit as TB's start to open
