Fuel Cut problem!!!

[johnnydogg69]

Hey guys im having a little problem with my MSP..Ive installed a front mount intercooler and a 3 inch catback exhaust system. Ive also have a Greddy RZ BOV...Im boosting top 9 pounds...but when i full throttle the car i get a really bad fuel cut when im on 1st, 2nd and 3rd but when i hit 4th I could full throttle it...my question is why am I hitting fuel cut if stock injectors are supposed to resist 10 pounds...Ooo and I also have a new fuel pump i think its a 450!Well hope to hear from somebody soon!!!and if i really have to put new injectors which one should i put on my baby!!!Thanks!!(mspb)

hows the spark plugs? Your MAF relocated?

Ive actually did change my spark plugs not too long ago!!!

Do you have a boost gauge? I see that you said your boosting 9 pounds. Check your spark plugs make sure they are gaped right and you are not getting spark blow out. I would actually check my wga first to make sure thats not the problem. If you are still having issues I have a brand new FCD, with instructions. If you are interested I can post up pics.

Boost 10lbs isn't the same some places as it is others. You being from wi it's cooler there now than some places. Colder denser air can max out the voltage in the maf faster. I had to run a fcd to come even close to 9lbs in chicago in the spring or fall. You will need some sort of tuning or fcd or to lower your boost.
