Anyone running FIC 1120cc injectors??

[BIRDCLAWTSi]

Just wondering how your idle is?

My car idles like it has a miss, wideband swings all around from lean to rich,
and stalls when I come to a stop.

My fuel pressure is set to 43.5 vac line off, My Deadtime voltage offset is correct per FIC's data sheet and my injector scalar is correct.

I have tweaked my maf comp and the STFT hangs around 109. Yet still swings lean and stalls.

I have made some minor adjustments to the deadtimes although I prefer to use the maf comp table.

Is anyone else experiencing this?

One more thing, The side of the injector is stamped 120 lb/hr on the black plastic part, Yet these injectors are the new 1120's and are engraved with 1120.

These are brand new.

Prior to this I had PTE 680's and had them dialed in perfectly without issue, Granted the 1120's are quite a bit bigger, I was just expecting an easy set up after reading all the great stuff about these injectors.

I should also mention I am using Tunerpro and my profile is current aside from the injectors.

Do I need an injector box?

Thanks,
Dave

You wouldn't need a box with anything smaller than 1450cc, but it might help in your case.
