Need Help! 2016 Mustang GT, 18+ ported intake, IMRC removed, "Insufficient fuel flow"

[Covfefe Mustang]

I am tuning a 2016 Mustang GT M6. It has a ported 2018+ intake manifold, Roush CAI, IMRC's deleted, cleaned stock injectors, long tube headers, no cats. The car feels decent on power, but it seems to be pulling power up top. Around 5,000rpm under WOT conditions, it shows "Insufficient Fuel Flow" and "TQ Red<Driver Demand". The car shouldn't be running out of injector or pump in my opinion. Am I hitting a limit somewhere? Please Help!!

Thank you!

try adding 20% to all of the DD gear shift tables only at the 90% pedal position area & changing the max injector DC limits to say 300 & see what happens, ive seen some tunes where they have 500% DC in these tables?

see how you go

It makes me force it to 300. It says 200 is max. Should I force it to 300%?

Why are all your toque values and wot load values all the way they are?

I used to have the same issues, i have a gt350 manifold, gt350 jlt cai, “free-flowing” long tubes, i resolved it by setting DD tables to stock, dialing my maf and setting my wot enrichment requirements to disabled.

Which torque values are you referring to? The WOT load values are the same as the stock file.

Post your stock file

Post your stock file

Can you set your airflow>general>airmass correction + traction control+ transmission torque reduction back to stock, do another pull and send the log, make sure you log "engine brake torque" and "etc torque request" in your graphs on the new logs. i have noticed that your driver demand tables are not any different between you tuned file and your stock, however my stock settings are much lower than yours. You can also enable map point "op" if you wish.

I can fix

Any updates?

I?ll try to add log and file later today. I ended up making the changes to stock on the geared torque tables by referencing a different stock read. Seems that the problems went away. Car was moving about 48.5 lb/min of air, which I think is better than what it was doing before. Thanks for the help!

[Cranked Automotive]

48 lbs is great! Thats about where im at around 7250rpm with 94 octane 26 degrees of timing and bolt ons. (Gt350mani, jlt gt350 cai, 170* thermostat, catless long tubes)

Could you help my tuner guy out? He cant tune my f150 2018 with the boss intake manifold on. The truck is not getting enough fuel at high rmps and the fuel pressure desierd drops as well

well f150 is MAP not MAF you need to rework your SD model.

[Edwardwbe]

Yes my friend i know. And i changed the sensor there on the back as well from the stock intake manifold to the boss intake

[engineermike]

Need log and tune.

[Dramex72]

could you help me i have 18 manifold on 2020 f150 it is going very very rich 0.64 l

should i post the tune and log ?
