Only sputters when i'm not WOT

[tbonitz301]

Just like the title says. My car only misses and sputters when im cruising. When i go WOT it runs great. I'm running 10 psi for now on a 16g. Any idea's

Please guys. I dont like bumping my threads, but i really need help on this. The 16g was just installed, and now im having this weird sputtering issue. It's not a boost leak, and it almost always happens when i'm boosting around 5psi or less, but like i said if i stab the gas she takes off.

Did you check your spark plugs? Sure they are gapped correct? I had issues missing and changed spark plugs and gapped them and dont miss anymore.

The plugs are new, and show a clean burn. I would think that if it was the plugs it would do the same at wot

My injectors were fine before the install. I run a bottle of lucas every five tanks. Thanks for the suggestions...keep them coming.

Have you logged it while it is sputtering (ie bad O2 sensor)? Is you wideband showing anything? Is your SAFC setup correctly for 750cc injectors (which by the way is kind of big for an SAFC)?

Yea about the injectors i gotta keydiver to compensate them. I havent logged it yet, but i will if i dont figure it out soon.
