Supercharged 2012 ss
Hi guys I have recently finished building my 12 2ss to lsa. I will include all parts at the end of thread. I'm having a problem. Chopping start and when boost comes in the car falls on its face on the dyno and stand still rev. I have installed a fore innovations duel pump fuel system and it reads 58lbs before boost and 62 during boost. I'm at a loss as well as my tuner any help would be appreciated.
Texas speed stage 3 blower cam Fully ported blower manifold and snout. 2.33 upper pulley Nick Williams 102mm tb 1000 cc injectors

Fuel pressure is fine. Have you tuned for NW?

Also are you sure the boost valve is adjusted correctly?
https://www.camaro5.com/forums/showt...nt#post8290240 Also only 1 vacuum line on the boost valve as the other line can shut off the valve. Which version of the NW 102 do you have? The NON-SC versions have been known to suck shut and stumble... that model # is: SD102MMEL: (DON'T want this one) https://www.summitracing.com/parts/nwp-sd102mmel You want the SC version (SD102MMSC): https://sdparts.com/i-24080932-nick-...lications.html as it has a stronger motor to prevent the sucking shut of the throttle blade... I have the NW 102 SC version and RPM's 5" CAI -- tuned by ABADZL1 and myself... No issues running that combo... Need to dyno again -- added meth too... -Don

Which brand injector? Did you load the injector data? Do you have the tune file?

If you're data logging, you should be able to see what's happening, like throttle closing, fuel or timing cut, etc.
