fuel cuts off at 5PSI??? Options

[StreetRacing10PS...]

ok so i made a new boost controller that works better and i got it to 6psi for the 1st time but some times around 4-5PSI it makes a funny thrthrthrthr sound and the car loses power. iam thinking its some how related to the map sensor because i dont think its reading boost and the fuel gets cut off. i even set my safc-2 to 0% correction. any ideas????

no, i herd u only have to adjust timing at higher PSI like 10 plusand now my throttle response is messed up, i floor it and nothing haoppens but i only think that the wire from my ECU to the safc2 is loose cuz its the ONLY 1 i didnt sodder togeather

I retarded my timing even at 5-6 psi and i would always sodder any connections for the ecu other than that how is everything?

found out the wires were fine. from under the hood if i rev it the little rubber piece under the throttle gets stuck and dnt pop out when the throttle cabel is moved. only thing really conected to it is a vacumme line to the intake.
