Hello everyone,

Short self introduction. We are a business providing OEM refurbished American vehicle engine controllers and we only deal with stock programming with very limited knowledge about tuning
(we have HP tuners and EFI live but we use them for very limited reasons). I have a customer who has purchased a 2007 Jeep Wrangler tuned and his PCM is bad. We have programmed the PCM to the latest stock calibration using Wi-Tech but since the Jeep that he has purchased has been modified, he needs the new PCM tuned. I tried to read the tuned file from the old PCM and I keep getting the Checksum not Valid error (I think whoever has done the tuning wasn't necessarily one of the best tuners out there and that's why the original PCM is not functioning properly). He needs the changes below and I promised to post on this forum hoping one of you guys expert in tuning help him to have his Jeep up and running.

1. 35" Tire front and rear
2. Performance exhaust without Cats but it has the O2 sensors
3. Cold Air Intake

Thanks to all of you in advance and looking forward to hearing back from you.
