well it's not a boost a pump but a nitrous pressure regulator to spike fuel pressure but another way is to add bigger injector's to compensate?

 

How would a "nitrous" pressure regulator add more fuel?

Yes, on the stangs, whatever it's called does spike the "fuel" pressure to compensate while spraying, where our cars use the MAF to read the colder intake charge of the n2o and add the necessary fuel.

 

Not knocking your methods, but I hope anyone running nitrous is having there cars tuned. With all the differnt methods of tuning out you can run n/a tunes and nitrous tunes. EFI has CO#5 plus there are plenty of other methods to dial in the a/f vs turning the nozzles.

 

The point is, and the fact is, without nozzle tuning or getting it right from the get go, yes, bandaid methods must be used and most affect n/a tune, except for the EFI live, but you must have your laptop hooked up to switch tunes. Whereas, nozzle tuning and setting PCM tune-up to pull timing allows a true two tunes in one and no need to run a laptop or timing box, that's the real point in the nozzle tuning ie: location/style/distance. Also, this method has zero affect on n/a tune. What ever works though, yes many ways to skin the dry cat, and more coming, stay tuned.

You dont need a laptop to switch tunes just a toggle switch and you do it with the car running. I switch to my n20 tune after my burnout, I have two arm switches, one cuts on the gas and the other switches to the n20 tune which allows for differnt timing and fuel tables.

 

Wow, we learn something all the time. In another thread when we were talking dry tuning and EFI, and there was plenty of EFI users and one EFI vendor, no one countered the need for a laptop as a efi down fall. Good news really, another great option for dry users who are looking to get a tuner program. So the two tunes in one in the stock PCM also applies to EFI with Coss 5? HP Tuner is no longer the only kid on the block.
