I am looking to adjust my fuel pressure and some other upgrades to support my nitrous system.
Do we have an external fuel pressure regulator...that you could swap out with an adjustable fpr?
From what I see.....or actually don't see, this looks like a return-less system, with the regulator built into the fuel pump assembly/hanger? (much like the late 2003+ corvettes).
I know one solution is putting in the 340 pump, replacing the stock pump.....but where can we adjust the running pressure?

you do not need this. for one you have cast piston in your car. running more then 150 shot is not recommended. Second just tap into the fuel port and run it as is. I have jetted for a 200 shot and it was perfect. otherwise you are wasting money and seting up a disaster in the making.
i have a creampuff (cast piston) and i spray 200 and i havent had problems but i use propane for enrichment the car made 626rwhp 861rwtq and it is going on the dyno wed to see if the new sct handheld programer is gonna be nitrous friendly but my car runs super rich.

Just digging up an old post here......
Gagedady, how did it work out with the new SCT programmer? Any benefit and how about tuning parameters you adjusted (actual vs advertised). Could you change timing including IAT affects?

not good i installed it drove to the dyno it felt great really felt like alot more power on the dyno it made at peak 10hp and 26tq but through the midrange it was up 20+ hp up until 5000 then it settled at 10 torque was also up 35+ most of the time except but peak #s were only 26 but because it had more under the curve it was good i dont know if it was to lean the highest i say it on the chart was 13.9-14.1 which is lean but not crazy but i ended up melting two pistons on motor on the dyno it probably was hurt from the hundreds of passes i made on spray but it is getting fixed now and i am gonna put the sct in the classifieds because i dont know if it is nitrous friendly .
but i think they can do a richer tune for you to run spray they new what i was doing with it and on spray all my a/f were 11.0 and under i think it may have been my motors time. the sct you cant ajust i thought you could but it came with two programs they set up for my cars mods (supposedly)in retrospec i regret getting it as i could have got a vec for a few hundred more. dont let this scare you i was probably close to 700rwhp and over 900rwtq and thats too much.

Appreciate the reply there Gagedady. From what you're telling me, the SCT is 'controlled from headquarters' with 'their' tune. Hopefully, it will evolve more into a HP Tuners program in the near future, eliminating alot of going back and forth feeding 'headquarters' dyno/afr numbers for fine tuning. I'll stick with the VECII for my nitrous tuning. Sorry to hear about your 'melting pot o pistons', sounds like things may have gotten hot and lean on the dyno. I'd hate to think they were running her hard and ignoring the air fuel ratio readings. Good luck with the build.
There was your mistake. I believe anyone with the sct software can modify and write the tunes set into the sct handhelds like roe does. The problem is Roe tunes it for one viper and mass programs what was good on that car and uses it as the base for all the units. The fact is you can log a/f or 10 vipers from similar Gen years and get varied numbers! It says to tell him the mods you have from custom programming but that's bullshit. If you have a borla exhaust with BB headers and he has a corsa with Bellengers, Your getting that tune. NO GOOD. When someone wises up and buys an unmolested SCT handheld and takes it to a shop knowledgable with programming them using a dyno logging a/f. You should see very goods returns from your investment on them. My suggestion would be to have a mustang tuner familiar with sct do your tuning. It sounds odd but the stang tuners have had sct software for a LONG time and the know what it can do much better then the seldom viper tuners like Roe that just started tinkering with it. I love Sean Roe and hate knocking him but it is the Gods honest truth.
I've never quoted myself before but.....I saw that one coming, unfortunately, it was from experience. Hope the build goes well!
to be fair i ran atleast 50 15lb bottles through it and i think it may have been hurt when i had a fuel (propane) solinoid stop opening at pressure so i was spraying it with no additional fuel a couple weeks before the sct was added.
i had one piston that was broke across the top edge and missing an inch chunk it must have went out the exhast but the ring was still intact so it wasnt noticable there was alot of carbon buildup on it so i was spraying it and driving it like that for a while.

that's why nitrous sucks. 50 bottles at what, 60 bucks to fill a pop. I paid 40 to fill my 10 pounder. You spent 3k of go go juice with nothing left to show for it. You could have been halfway to a Roe blower by now. Now with the fubar motor repairs plus the juice expense you could have purchased a paxton kit and been running 750 hp to the tires all day long.

i agree and you have to factor in the 1600 dollar kit plus heaters gauges but it was like financing horsepower. but also the roe would be a 5 lb kit or maybe 6.5 and it wouldnt have made the same #s now a paxton kit would have been better but to get it installed properly and tuned on a creampuff it was gonna be 15k+ and it still would break the pistons with any big power. I was talkin to kevin about a blower install and paolo and they can make the power but for how long.
today i tried to bite the bullet and go street strykers cam ported intake i got psyced up and doug levin called jeff and there are no more gen 2 strykers available until after the 1st of january so now i depressed.
Can you adjust fuel pressure on 2002
