Where is your boost? At 800 your DC% is high (WOT?), but your boost is only about 8 psi! (22psi MAP -14.2 psi BARO (estimating))

Somebody check me on this

i have a "fooler" type rig on my map line. harbor freight 5$ air line pressure regulator.
have a gauge and electronical sending unit with it mounted in the aih delete plug.
i saw 28psi on a wot run coming home from the shop today.

yes i think either the bully dog tuning is jacking with my ipr and icp values or my pump IS on the way out after all...

wasnt paying real close attention to the laptop while my foot was in the floor for the test runs while recording. i saw the 12%ish area it was at for idle and started to get optimistic.

dang it Tugly!

Got a chuckle out of that one.

With that ICP/IPR, I would dump the MAP (which does little good with a fooler) and look at the FIPW. Once that was done, I'd repeat the test without the Bully Dog. You may yet have cause to be optimistic.

i know i said i was going to do just that like a year and a half ago or better but never got to it. i was kinda subconsciously waiting till she got new sticks.

took a little 20 minute drive last night to return a bulldog from whence he came and saw my overhead climb from 22 to 23.5 mpg. we call it a lie-o-meter for a reason... but it has never lied to me like THAT before... my hand calculated economy is usually right at 2mpg lower than overhead avg... im extremely optimistic!

16-18 MPG would be more realistic with those big hips on Motorbug.

i agree. with it creeping up on 24mpg on the overhead im going to lean on the high side at 18.

now im itching for a road trip...

i dont really want to go anywhere... but it would be less boring than 1000 miles worth of driving the loop around the giant metropolis of Victoria lol.

i did not get to pulling my chip today... had to bring a few one off oddball parts into existence then tend to the manual lathe the rest of the day...

tomorrow is looking less busy...
