There's an update to the "updated" flash in CA (and other states). The
original flash took out some timing that caused the engine to
perform...well...much worse than one would like.
You can, however, alter the TPS voltage slightly (set it to .7v at
Key-ON/Engine-OFF). This will help out on the initial and overall
min/max TPS setting.

Subject: DML: California PCM flash/Throttle position question
Hey guys,
Had my truck dynoed and I was a little disappointed, but during I found
some things that aren't normal. While on the dyno we hooked the truck
up to an OBDII program and at wide open throttle the computer showed
that the throttle body was only 74% open. I checked voltages at the
throttle postion sensor and it showed only 3.8 VDC. It should be 4.8
VDC. I was wondering if anybody else had ever checked their voltages at
wide open throttle.
Also, I am unfortunate enough to live in CA and I had to have my PCM
re-flashed by the dealer a couple years ago for some emissions TSM and
ever since then my truck has been noticeably less powerful. Wondering
if you guys had any info on this TSM or if it had anything to do with
the low voltage readings on my throttle position sensor.
The truck is a 98 4x4 5.2 5-spd.
