Car is tuned through hpp racing. Im having an throttle code pop up. P0241

Car is on id1700 injectors, dw400 pumps, absolute ripper and only runs on e85.

Recently i was wot and got a wrench after a loud backfire (probably fuel cut). I limped the car home and shut it off till next day and it was fine for 2 weeks, i didnt have a code reader at the time and some random performance shop said they didnt find anything at the time. Today i changed spark plugs thinking that would help, and ripped the car for a solid 15 minutes, (4-5 wotpulls). Turn it off and 15 minutes later go to drive it again, at 45mph cruising off a light, here comes the wrench and limp mode again, shocker. I cleared the code with a cheap obd reader and car is fine again, drove it for 45 mins super conservatively and no issues.

Maybe my throttle body is faulty? Anyone have experiEnce with a similar situation?

Will call roush in the morning before i take it to my tuner and see what they have to say. Maybe its a tune issue? Idk man
