Boost Problem, please help

[silviasx720]

i just recently started having problems with boosting past 15 psi. ive had the car tuned with the power fc d-jetro, and it was running about 11.7 on the air/fuel at full boost. But now every time i hit about 5 pounds, it runs extremely rich and bogs REALLY bad when it goes to 15 psi and wont go past it. its like the motor wants to stall.

List of mods:
sr20det black top
arias pistons
eagle rods
hks 264 stage 2 cams
percision gt2871r .86 a/r
greddy valve springs
3 angle valve job
apexi power fc d-jetro
hks bov
custom 3" exhaust
greddy front mount
exedy hyper single clutch
b&m short shifter
apexi avcr
aem uego wide-band
sard 680 cc injectors
walbro 255lph pump

307whp at 10 psi, 388whp at 19 psi (clutch or tire slipping and mis-firing)

Im sorry to make the list long, i just didnt want anyone asking what this are u running or what that are u running. Please help out when u get a chance. thank you

what plug gap/heat range u running?

[silviasx720]

the only thing, unfortunately, that i know about my plugs is that it is ngk 3330 i think. and iv had misfiring prob on the dyno, thats why i couldnt get it past 388hp. after all that i still could hit 19 psi. now i cant.

you got data logit? can you monitor the ignition when it was breaking up? and even further if you could isolate the cylinder....could be the coil packs *shrug

[hello]

check your ignitor chip. swap it with someone elses or something. also check your coils.

[raysurz]

Check your spark plugs. Might have 1 or 2 foiled out. That would be the easiest thing to try first. Buy new NGK plugs (10 bucks). Gap them to 27 to 30 and give them a run. If it doesnt help, then has to be something else electrical to the ignition.
