didnt want to do this, getting crap about dry, help with an argument
didnt want to do this, getting crap about dry, help with an argument I have held off on this for quite some time. I have the NOS5177 kit on my car. 90jets in it. Sprayed 125 3-4 times, just want to hold off on that till I know its ok.
Here is my thing, I have a local tuner that is constantly bashing me for running a dry kit. For some reason he seems to think using info I get from ls1tech is not good enough. He also seems to think the max an ls1 can spray is. Well I will tell you what, I'll just quote the guy.
Arguing with this guy online is pointless, but I sure would like to say, hey look here.

In Jay's setup, you spray nitrous directly into the MAF, which "somewhat" detects the colder, denser air charge and will indeed add "some" fuel. But he runs a STOCK TUNE in his PCM. And the computer has NO IDEA that the car is running nitrous. So what does the computer do? same thing it does coming off the showroom floor: it runs a mixture of, best case, about 12.5:1 AFRs. (for the uninitiated, including Jay, this is a LEAN MIXTURE). And it runs a factory spark map, which is not meant to support a power adder. I might add he is running pump fuel with this same mix.
I should add that no data logging has been done on my car yet. Its just a constant yacking that this guy does to make it seem like my car is about to detonate from running a dry shot.

So what does this "tuner" recommend? Don't say a wet kit because it for damn sure won't do anything to fix the "factory spark map" problem. Obviously, a dry kit going through the MAF will do something. Has this "tuner" actually tuned something before? Or is he just some high school drop-out type that does oil changes at the local WalMart/Pepboys/[insert favorite rip off oil change station here]? And for what it's worth I was always in the 11.5 - 10.8 A/F range. Rich, I know, but lean it is not!

My point is running 75-125 is not a problem. Especially when all i am running is 90shot.

let him think what he wants. Dont do any business with him since he has no idea. 
Does he have a dyno/wideband? Best bet would be just to show him how your car/maf handles the dry shot.
If you have a wideband and tuning software you can make some logs of your runs and show him.

Have him come here and state his case for scrutiny.
We should be able to reason with the man eventually.
There's more than enough documented log data to show what is going on.
For the most part dry systems are very simple and work well with very small amount of risk involved.
If he doesn't want to trust the operation of the MAF, I can understand that.
Running dry systems in SD or OLSD mode is obviously another option for dry and that works well too, just not as simple.

Well im not a fan of maf or dry but saying that its not safe is just dumb if you have fuel pump, injectors and a tune (a tuner should love dry kits more money for him) your safe as any one running a wet kit with a fuel pump.
Get a new tuner. Many tuners, even the "Good" ones, have no clue how to tune a dry, and/or don't understand the concept totally. There are many, many ways to tune a dry hit. A small hit really needs not much of anything tune wise. With out going into the tune, nozzle placement is the most critical for a/f. I run anywhere from low 11's to high 11's with just nozzle tuning. Like white2001s10 said, if he has the grapefruits, have him present his case here.
