2nd Gen Non-Engine/Transmission 02 ETH boost question

[Sticks]

Well, I guess a variety of gauge output questions



I finally got some gauges for my baby (thanks wife). I did the install over the weekend, and here is what I have seen so far;



Idle

FP is 14 - 15 at the VP

EGT jumps to 300 at startup and eventually falls back to it after running.

Boost is 0



65 mph cruising - level ground

FP is 13

EGT 600 - 700

Boost 2? If there is a slight incline it moves to about 10



Hard Acceleration

FP ??? Haven't looked yet

EGT peaks at 1000

Boost 30 (is this normal for an ETH with an EZ and stock injectors? Seems high) then drops like a rock if I let off it even a little. It acts like I cut the hose. 30 to 0 in . 10 seconds.



My main question is does the boost numbers sound normal for my truck?



How about the rest of the numbers?

Those are the numbers i saw with my EZ and stock injectors. Although, my peak boost was around 33#.

EGT sounds right based on my 01 numbers. Boost seems a little low for that speed. Usually at 65-70 the lowest boost I'll see on flat ground is 4-5 lbs. Slight inclines, I go to 7-9 psi.

EGT is about right. I've hit 1350* towing. I have SPA digital gauges and they store peak numbers.



30 psi boost seems kind of high simply because the wastegate should open at about 21 psi. If you have the wastegate disabled then you probably are seeing 30 psi. My wastegate is stock and I've seen 21 towing. I'm not sure how yours bleeds off so fast unless you are seeing a peak before the wastegate opens.

I assume that's a post-turbo EGT reading?

The boost #'s look fine to me. My truck acts the same but, I have the boost elbow installed. You don't state whether you do or not, so I'm assuming you do! If not that seems high... Phil

I have '02 ETH with gauges and stock. At idle is about the same. Cruising at 65 my boost runs around 6-7 lbs. will raise to 10 on a small hill. Everything else looks normal to me.

Cool! Thanks guys.



Yes I do have a boost elbow installed.



The EGT is Pre turbo.



The water/meth injection is off.

His temps sound right in line with my truck in stock form, pre turbo.
