hi, ok here is the problem i have. hope sombody could help. i got a cell p2020 a intake runner position sensor out of range bank 1. i call the sub and they told me it is common problem on sti. they have to take intake out and repair whatever causing the problem. my question is if i delete the tumbuler valve or put jdm runner, using st can i delete the cel once i took the tumbuler valve out? yes i call the cobb and he wasnt 100% sure. so i was hope did anybody replace the tumbuler valve with jdm runner and delete the cell? or should i just fix the problem.

Get an APS TGV delete.

p2020 is not listed in my ST SW as one of the CEL's it can defeat. the PT (pro tuner) SW would be your next step.
