instead of using stock injectors, intank pump and FMU i was thinking of using


450cc DSM injectors and VAFC hack

would i still need the intank pump?

 

no, you would not. The purpose of getting the bigger pumps is to supply enough fuel at higher fuel pressures, which without a FMU you, you won't see ultra high fuel pressures. The stock pump is sufficient

 

so i can basically throw out/sell my intank pump and FMU and have no problems?

 

you got it! Make sure you tune it with a wideband though

 

i dont have a wideband

but was gonna just not run above 5-7 PSI till i get it tunned and hope that the autometer a/f gauge stays green a WOT

 

search around and find a dyno center in your area. http://www.dynojet.com is a great place to look. Many dyno centers have wide band o2's. A good safe setting is -37% all the way across. Definately be easy on it before you get it tuned though

 

only one near me is

D R T Inc.
50-33 73rd Place
Woodside, 11377
Tel. 718-397-8586

and they aren't too cheap

as long as i know that the 450's and VAFC hack will work with nothing else i'm happy

 

also shgould i leave the fuel pressure at the stock 35? or should i raise it up a little

 

Clayton dyno here!
