bogging before 4k rpm

[Revere sho]

i was just wondering why my car is doing this, anytime i push the gas more than half way down before 4000 rpm in my superchargered sho, the car starts bogging but anywhere after that it dosent happen in all gears except for 5th only cause i never went fast enough to test it. i have a fuel preasure gauge and when that is happened the nettle on that goes nuts bouncing from 20-80 what ever units that is.

do any of you know waht that is?

thanx again for everyones help.

to be more specific it looks like i am sending more fuel than air and when the secondaries open up then i have a good enough mixture then but thats only a guess does that some right?

if so how can i fix that?

Check your cam position sensor

What fuel pump are you running and what size injectors? Which maf and what are you using for tuning?

I had the same problem in mine till I cleaned my MAF. Anything more than about half throttle would cause the engine to bog down and stop accellerating, but anything under half was fine. I cleaned the MAF and it totally fixed it. It's an easy free thing to try first at any rate.

My guess is its running pig rich at low RPMs, which is fairly common with boosted SHOs.

Ya Its Running Rich I Mixed The Two Words Up Ya It Runs Really Rich Below 4k Rpm.

i just found out that the car dosent have any big bore butterflys, no ported intake, i believe no 80mm maf and i believe no 68mm throttle body. im going to measure them tomorrow to try and tell. also the kid says it has an upgradable computer. is there a way that i can tell if its that lpm.
