Do I need to retune Or This Tune Safe To Run?

Hi everyone!

I’m new to this group—I hope you’re all doing well!

Mod List:

COBB SF Intake

Grimmspeed Catted Downpipe

Invidia Q300 Catback Exhaust

NGK 1-Step Colder Spark Plugs

IAG AOS

Grimmspeed 3-Port EBCS

Turbosmart 40mm External Wastegate (Comp-Gate40)

ID1050X Injectors

AEM 340 Fuel Pump

Radium FPR Kit

I recently bought an STI, and the previous owner mentioned it was tuned with dimemod. I’ve been monitoring FLKC, FBKC, IAM, and fuel corrections (long and short term), and everything seems fine. Occasionally, I see FBKC at -1.4? -2 low speeds between 2400-3500RPM, but IAM stays at 1, with LTFT and STFT under 8% in closed loop and under 2% in open loop.

While reviewing the tune file, I noticed the MAF scaling table isn’t as smooth as the OEM tune (screenshot attached). Do I need a retune?

Also, just out of curiosity, what are these four tables used for?

1. Knock Correction Advance Map Additive A (IAM)

2. Knock Correction Advance Map Additive B

3. Knock Correction Advance Max Primary Cruise (IAM)

4. Knock Correction Advance Max Primary

For reference, I’ve attached timing and fueling tables as well.

Thanks in advance!
