I recently got my tuner I purchased from PPEI I got the dps5 switch and the trans tunes as well. I am trying to figure out how to go into the tuner and turn the EGR off. Hopefully I didn't waist my money if anyone knows pleas help. Thanks
Yep PPEI is all emissions compliant tuning. An autocal, which simply loads your tunes (not allows you to adjust). And yep, they likely are locked so we cannot all copy their extensive work perfecting their tunes.
