I just bought the new predator. u7198 V9r15 Im trying to get my truck running right but am clueless. I cant put in a custom tune because i dont have the computer cable yet. Seems like it is running rich. Engine is the 6 liter. Cold air intake. Edelbrock headers. True dual exhaust. No cats. All 4 o2 sensors are still on exhaust. Anybody have an idea as to what to do?

well, to get a custom tune to disable the cat and rear o2 codes, you're going to have to get the power adapter and usb/serial cable so that you can connect the predator to your Windows PC so that you can import/export tune files and get a custom tune created in order to disable those trouble codes...

you'll also need the cables to you can connect it to your PC so you can download the data logs from it...

by doing and saving/recording data logs, you can get your fueling dialed in correctly so that your average ltft's are in the proper 0 to -2 range and you're not running so rich...

BUT... first step is, you need to get the power adapter and usb/serial cable so that you can connect that puppy up to your PC...

watch the ltft bank 1 and bank 2 numbers on the screen while you drive steady at 1800-2000 rpms on the highway...

see what your ltft's are reading, then adjust your injector slope the opposite amount...

then get the cables so you can save/record data logs and download them to your pc... and will be able to import/export tune files if you want to get a custom tune down the road...
