still sputtering/bogging

[dale187]

Was suggested to change the spark plugs and wires. Used the bpr6es' and BWD wires. Got on it and as soon as boost started hitting hard it started sputtering terribly. Any suggestions?

How much boost was the car making? Did you do a boost leak test?

It was reaching 15psi. And no i did not do a boost leak test yet.

I was just going through that as well this week actually. i had bpr7es plugs in mine and replaced them with br7es plugs with ngk wires and i no longer have that problem. however not everyones cars are the same setup though. just thought i would chime in considering i was having the same problem.

I would recommend you do blt 1st. I made my boost leak tester from parts at lowes hardware for about 7 dollars. Plugs made a difference in my car cranking before. Using 6's instead of 7's.

I would recommend you do blt 1st. .

i agree that would be a more efficient test

Are the plugs you are using platinum? If so go get the copper ones because the platinum ones have very small spark points and at boost the pressure might be putting out the spark.......... I run 20 psi all day on a semi daily driver and copper plugs will never be replaced by platinum

P.S. NGK all the way

also make sure the plugs are gapped properly

fuel pump? injectors? i got 255 walbro n 680cc injectors.. i just ordered my fuel pressure regulartor because i got it tuned and soon as it hits booost the regulator cant keep up witht he pressure from the 255 pump and just loads it upp. just my 2 cents.. so on my car wot it sputters pops n all due to to much fuel.

try the fuel filter, fuel pump, or injectors. as far as them being all new and clean parts.
