Upgrading my U7135 Predator

[sconnell80]

I have a u7135 predator for my 06 SRT8 charger with 9r04 I do beleive. I wanna know if I will be able to upgrade to the newest crom so I can get the MPG booster and throttle booster. Thanks in advance guys.

I just confirmed that I have software 9r04 with hardware UNIV_REV2. I was just curious if I could upgrade to the 9r29 crom or if I am stuck at 9r12 crom? I would like to get the MPG booster on my car. I know I would be giving up the option of turning off my 02's but I dont run headers or high flow cats. Thanks in advance if anyone can help.

You can go all the way to 9r29.

Ok thanks. As soon as I get my cables I will do it. Is there anything else positive about the 9r29 that I dont have with the 9r04? I know I will lose the 02 shut off option correct? Anything else I will lose? Thanks Mike.

Throttle boost is the best reason to do it. You'll lose anything that affects emissions. O2 delete, EGR delete (not an issue with the 6.1), and anything else that would make an emissions device not function as designed.

Ok thanks Mike. I dont care about shutting off emissions devices, I want my car to run the way the factory wanted it to and so I can pass NY inspections. I dont race it just street driving. I would like a better throttle response. I also wanted to try out the mPG booster. Any little bit I can get some better fuel mileage out that 6.1 is better. Alot of times my MPG's on my EVIC is around 22-26 MPG. I know that is better than most people get but I take it easy when gas is up there in price. Thanks again Mike, I will upgrade as soon as my cables come in.
