    Is there anything other than the fan temps that need to be changed in the tune for the T-Stat? Like any codes to turn off?

    re: RATTLE Snake Bite the XLR-V

    Coach123 has the snake bite on his stsv he has 60s for fuel injectors and made 445rwhp479tq if I remember right. I'm hoping with the meth to not need biger injectors. Yet and with my cats out of the way I should be good to go if the fuel pump is up to it.

    Cam timing is needed to be modified to take advantage of the new found boost. It will let coach exceed that 445 mark.

    As for what needs to be changed for the thermostat, it would be a few fuel learn values, like o2 settings and closed loop stuff, then you have to just delete one code for warm up stuff. It is pretty simple.

    re: RATTLE Snake Bite the XLR-V

    The XLR-V has the same 42lb injectors that the STS-V does, right? I'm surprised that they are maxed at only 430hp. Mine are at 86% at 400. You guys must be running a richer AFR than I was.

    I am interested to see how the new injectors will idle. 90lb is pretty big.

    Timmy, it is the torque that is the fuel consumption issue. He was at over 500 for a breif amount of time that low. Before hp even became a factor...

    re: RATTLE Snake Bite the XLR-V

    Ah, I did not think about that. My torque was nowhere near that, 400 was my max.

    You probably know what the connector and height on these injectors is, could you tell us?

    re: RATTLE Snake Bite the XLR-V

    Still seams odd are we shore that it is not the fuel pump is maxed out. I had 42s in my camaro with a much bigger ci motor 6.0l with a gt67 turbo 10psi 498rwhp and 521rwtq over 400rwhp and 420rwtq at 2,800 rpm. Ran out of fuel then up graded fuel pump and the injectors were then only at 90% duty rate. So I'm just thinking that a 4.4l should be good to over 450rwhp and tq with 42s so I think it might be the fuel pump. Do we know.

    If fuel pressure does not drop then no fuel pump is needed yet.

    re: RATTLE Snake Bite the XLR-V

    So the fuel pump is ok up to 450ish rw so far. I will be runing meth on my snake bite supercharger when it is back on the car and I have no cats and x-pipe with magnaflow mufflers so their is not much else I can do on that end. Do you think the meth will take care of the fuel shortage yes yes I know that is playing with fire but it is the cheap fix for now.

    im never a fan of meth. Just do what it takes to do it right. Bandaids can always fall off and get dirt in the wound...

    re: RATTLE Snake Bite the XLR-V

    I'm going to have my injectors resized so fuel will not be the issue as long as the pump can keep up. I don't play with fuel if it wants more I will give it more but the fact remains my turbo 6.0l with more hp/tq ran good on 42s. And why do you not like meth if it is set up right I have never had any problems with it. Most all my friends have turbo our supercharged cars GNs/c6/c5/cobras all with meth and they have had no trouble at all and some of them over 700rwhp. Just wanted to see y you don't like it.
