I'll look for those on the MAP and WG, thanks guys. The intended use is just as you guys speculated, DD w/ occasional towing. Also the truck is a 2000 not a 2001, my accord is a 2001 so I get mixed up. Does the trans issue still apply? This truck also has a transcommander as part of the stinger. Do i ditch that too when I order a PHP?

Yeah... the chip handles the transmission. Transcommander, eh? I never heard of it, and it's possible it's doing more harm than good. A lot has been learned since many of these mods were marketed.
I have a 2000, and there is no mechanical diode in the transmission - the bane of the 2001.

Tugly, I just read your "tuning" post. I just got my forscan adapter and will focus on that 100% healthy first than look for the tuner. I'll update you guys with what I find regarding the SES, and I'm sure I'll be asking for input as well. I owe you guys some beers sometime.

I also do have a ground tap on the green/black wire from my MAP, anyone know why?

That's the picture I showed you a couple of posts back. This was a very cheap (and unreliable) attempt to limit the Manifold Air Pressure reading (boost) to prevent defueling with overboost. It looks like just a wire, but the female spade connector has a zener diode in there, to electrically limit the MAP signal. It needs to come out, it messes with the performance of the truck.
If you find yourself in a situation where you want to limit the MAP signal, you're better off with a proper pressure regulator on the MAP line from the spider (mechanically limiting the signal). Most people never need this, because tunes prevent defueling - but some chips still permit the overboost "alarm" to occur (SES light on the dash when you exceed 27 PSI boost). I have a pressure regulator on my map line, but not because of any alarms - my chip prevents those. I exceed the MAP sensor pressure limit (35 PSI boost), and I already popped one. The MAP line regulator from Riffraff diesel was less expensive than the MAP sensor.

Got it, I'll remove it ASAP. I just got the new ICP from the dealer. (Luckily I used to work there, only cost me $130... ugh.) I also bit the bullet and got a AIS intake. I was think a 6637 but I think the noise would drive me crazy.

timmyboy76 - nice catch on the Singer mod... I forgot about those things.
jfuller429 - Funny thing about the AIS.... You won't know how good you've got it until you sit in someone else's truck with a 6637, AFE, or some other notoriously loud intake.
Good job on the ICP - you may very well have found a power sapper. The most common failure with an ICP sensor is it will read higher than actual. When this happens, the PCM dials down the actual ICP, and the truck gets very anemic.

The AIS is a great intake. I wish they made a 2.0 version with the airflow to match a 38R and injectors.

Amen, brother. I'd swipe my card through the ATM so fast the card would melt.

Do you guys know if I can simply remove my old banks chip and run the PCM normally? Or is there a process to removing a chip? I'm trying to get my truck 100% healthy before deciding on a tuner.

I looked for any extensive mods and don't see any.??? So, as long as your transmission is stock and the injectors are stock you should be fine. I can't think of any reason not to remove it for a test. Just make sure that the ignition is "OFF" and the key is either in your pocket or on the dash. PCM's are expensive.
Then, if it idles fine and revs fine, take it for a very easy test drive before you open it up.
It will probably be a bit slower.

Since there are two batteries, should he remove the positive on just the passenger side or both just to be sure?
I would recommend wrapping the connectors for the cables in a towel or something non-conductive.

Both grounds or both positives - whatever is easiest.
I would run as stock as possible (tuning wise, but get that AIS installed), then conduct driving tests with FORScan. This is how one learns the true condition of the vehicle without compensating for any tricks up the sleeve.
