so far the fuel pump seems to have been the issue. the walbro is working fine and i cant get it to sputter, even when driving like an asshat

I'm still stuck on mine, threw some coils at it today with no luck =\
Its not the plugs, coils, MAP, TPS, IACV... could it be the Kal itself in the Kpro??? Does the Kpro calibration change part-throttle (closed loop) settings?

Bump... just returned the "non-stock special order; no return" coils because it didn't fix my problem... : D
Fab, could it be the tune itself??? My TPS broke on the dyno... when I put a good TPS on, this problem started...

If the calibration was done with a damaged TPS, then it's possible that a properly functioning TPS could cause problems with the tune. Other than that, I can't see how two different TPS with very similar start and end position values would cause problems.

Re: Walbro Fuel Pump Comparison (190 v 255)
I just wasn't sure if the tune encompassed the low and mid-throttle levels as well as open loop...I just figured they left the low/mid levels alone.
Here's the story... on the last dyno pull, the return spring in the TPS broke. At Closed throttle, it read 30%. For a good chunk of the beginning throttle range, the reading stayed at 30. After about 1/3 of the way through the sweep, the TPS would start reading accurately again.
