93 Octane Predator tune installed; In first gear, with WOT acceleration, upon reaching 4500-5500 rpm occasionally an intermittent squeal can be heard from engine compartment...was told possibly CAI could not handle flow so replaced with JLT (an awesome CAI-was using Mopar)...still there...belt looks ...

I apologize for my endemic ignorance on many issues mechanical, but what exactly is the difference between a stock 02 sensor and a wideband 02 sensor; I am installing a Corsa cat-back system and would it be a positive move to add wideband 02s at that time to enhance the opportunity for a finer tune ...

I filled to the brim with 93 Octane w/10%distilled corn juice after running a tank with 91 OCT no corn juice...91 OCT/no-juice seems to run significantly better e.g initial pop and mid-range WOT than the 93 OCT/juiced...but 93 OCT seems to 'sound' better-engine rev etc...will be going back to 91 OCT ...

Finally navigated into my cranium...takes awhile at times!!...the next question: is the MTCM worth the price in terms of a SIGNIFICANT increase in performance etc. and/or is Diablosport any closer to inculcating an updated predator flash for improving the OEM TCM...

Thanks for the reply!! Not sure what I am going to do...my fans don't run all the time and I have heard the fans are rated for so many hours of run time that the latter should not be an issue in terms of replacement...but if the fans could be set to run less without endangering the engine I would ...

I am about to add a Corsa Xtreme cat-back system...do I need to run the 91 tune post-installation/or set the stock tune then add the system then re-flash the 91 tune/ or do nothing...I don't know anything about O2 sensors other than they gauge/control fuel mixture in some manner...have been reading ...

As per the MTCM back-up...after backing-up the tune with the MTCM installed does this mean I will have both the original tune with the stock TCM backed-up and a new tune with the MTCM backed-up on the Predator...in other words, two tunes that I can revert to depending on what TCM is installed ...

Same issue...but if it keeps the engine running well I can live with it...anyone know if it is detrimental to have the fan run more often other than the irritation factor?

I can relate to the elation of your initial tune!! I put a 91 Octane cai on my 2006 Charger and it produced awesome results, similar to yours...going to add the cat-back and try 93 octane gas...question: did you try the 93 octane with the 91 octane tune at all before loading the 93 octane tune? Best ...

Hey...thanks for the information...do I follow the same procedure with a 2006 Charger R/T?

As per my previous post re: MTCM...I was referring to the: Mopar Performance Transmission Controller Upgrade LX TCM P5153332 ID:P5153332...is this what is being discussed...I am considering buying/installing it...I have been told it was formulated to take out the performance glitches in the 2006 ...

Let me try to understand and distill what I have read...remember, I am a novice to this all, but with a fast car made much faster with a 91 octane cai diablo predator tune:

If I already have the latter tune on my car and add a MTCM the MTCM will sense the install and set the points to the proper ...

Hello fellow searchers for speed and fan advice (bad pun)...I don't mind have the predator tune settings intact when the air con is on as long as the setting is doing what it is supposed to do...but what is that?: to cool the engine at different settings because of load issues or to keep a constant ...

What is a rev limiter/how does it work...what is an upshift definition mode...under what condition/need for power should the latter be changed/altered...thanks!!

Hi...new to this...loaded the 91 octane tune...runs great...hear a fan coming on and staying on longer that usual with stock tune, while aircon is running...is this an aircon fan or some other fan...what are 'fan settings' exactly and how do they affect performance/engine if they are on more than ...
