guys im going to do the imrc delete and was wondering what happens with out retuning it? I will probably retune in the future but for now im going to run it with out a retune. Btw i had a complete tune done last year so im not on fords stock tune at all. Im tuned for 12 psi boost, 23* timing and low-mid 11 a/f. Will anything change by deleting them? I will be removing contol box(actuator and anything else involved in the delete) also the fuse from under the dash.
Thanks
Thanks
