i did not mention in my first post, the reason why the stock tune may be able to carry you is due to the COT protection, where the car runs rich. Once your car is warmed up, By the time you switch...

if i had it, i would have emailed it to you already. Its easiest to learn things when you can compare and see where they are different.

one thing i learned a long time ago, run away from people...

your guess is correct. The cars require more fuel at the top of 5th than they do all the previous gears. Since people don't have an issue in the first 4 gears, they assume fuel pressure cant be the...

so have you considered that the HP pump going up and down an extra 30% adds to potential wear and potential failure on both the cam lobe and the pump itself? Plus now you are messing with lash caps,...

that pro charger metal intake manifold that is usually black with red text, is the one most use.

I haven't owned or upgraded a stingray, ive always started at the z06 level, so forgive me. If others were chiming in, I would be all ears, but since they are not, i just want to point out why my...

60 on the low side is too low. Chances are, if your car is down there, and you arent throwing codes, your tuner may have intentionally or inadvertently disabled the p228c warning... but either way,...

i assume you 2 talked behind the scenes, and you explained all it to the OP?

Nice to have someone else on the forums who understands simple physics and likes to tell people the truth :cheers:
...

im not savvy if the z06 in tank pump can be used on the c7 z51, i believe it can, and Im 90% sure it is larger. However, don't mix match with 2019 pumps, while the 2019 pumps for the z06 are larger...

he's right.

Also depends on cam and supercharger or turbo and exhaust restrictions, etc.

And even then, it is still a trick question, as I explained in the first post. Lets say you make...

Im NOT a tuner with knowledge more than the others above. However, assuming fuel pressure drop is your issue...

cold weather, all cars intake more air and request more fuel to match, so a tune...

Its the cold weather and sea level at high speed. Reach out to me if you want to learn whats going on instead of listen to these guys who are on a mission to ignore what i taught them all long ago,...

his car... is stock.

And yes, the low side runs out of power long before the high side pump does on the pre 2019 z06 c7's. Its fact at this point.

Stay tuned higgs, Mike has already spoken to...

...aka... void your factory warranty, and tune your car... instead of make GM fix it under warranty?? Our opinions certainly differ.

And no, its not the cylinder being flooded with fuel. It is...

these guys won't understand or agree what the problem is. We can do it to any stock z06 lt4 (and now you can as well since you know the secret process). I'm the one who already has my lemon ruling...

I realize the o2 sensors are not meant to measure heat.

The only reason i bring up this request is due to a lead tech at a dealership telling me that he believes the o2 sensors can measure heat as...

right, when the car is first started in sub freezing temps, it waits to turn on since it assumes the fluid is perhaps frozen if there is no antifreeze in the fluid... keeps the pump from running dry

I am looking for LT4 o2 sensor voltages per temperature chart/table, please, on the downpipe, both the before 1st cat sensors and the after first cat o2 sensors.

Or if you can point me towards who...

The other concern is volume of water meth. I would imagine 8 nozzles flow more than only 2? Unless the pump can be maxed out with only 2? (Doubtful)

Frustrating. Then there is no guarantee the vapor is being distributed evenly across all cylinders.

one option is to inject the meth downstream of the screws, which would be the nitrous outlet blower cap that is pre ported for 8 meth injectors... but if there is not a true/accurate read from an IAT...

i am confused then... is there not an IAT sensor downstream of the blower on the LT4? Reason I need to know is for setting up where meth will be injected. Obviously I want the meth injected...
