Has anyone heard anything about getting the stock ECU unlocked. A friend said that Diablo had done it and that the stock ECU then becomes programmable.
I know exactly what you mean, that is why I went with Diablo and a remote tuner. I really wanted to go with a more hands on solution but after months of studying realized that I had neither the knowledge or skill to tune my own vehicle. Hope to get there someday. I have a lot of respect for board members that tune their own cars.I have a my stock PCM sitting on a shelf, I had a Scat pack 1 PCM installed in my 2015 R/T. I keep thinking about getting it done, but tuning for some reason makes me nervous, like afraid I will "brick" my car.
If I did my stock PCM I would still have my unaltered Scat Pack 1 PCM and the dealer can NOT flash that...Have you heard the phrase "Penny wise, pound foolish?"
That applies to your PCM. You might "save" money having your OEM PCM unlocked, but you're setting yourself up for trouble and expenses down the road.
Why? Because many dealers flash the PCMs when the car is brought in for service. If you unlock your OEM PCM and have a tune installed, when the Dealer flashes that PCM (1) they'll over-write that tune and if you don't have it saved you've lost it and the money you spent on it, and (2) the dealer will read that your PCM has been unlocked; this could (will) lead to warranty issues down the road.
IF you are interested in getting a tune, you're far better off buying an already unlocked PCM from HP Tuners or Diablo Sports, and only swap it out with your OEM PCM when you take your car in for service (takes 20 minutes max).
Strange things can happen to a PCM that's flashed by the dealer; if they "brick" your unlocked OEM PCM, they'll most likely deny culpability because it was unlocked, and you'll be stuck at the dealer with a very expensive paper weight (your car) unless you pay the dealer to replace the PCM....IF they have one in stock.
Bite the bullet and buy a second PCM that is unlocked by the tuner of your choice...it's worth the piece of mind.
Mine without cats was fine at hwy speeds and was noticeably louder around town, sounded pretty good. You would probably like it I am guessing. But, in the morning at 7 am it would wake the dead so I had to keep the garage door down and start it, it was frickin loud. I had to wait a few for it to idle down some, open the door and scoot out of the subdivision knowing I woke a few people up. Probably would be the biggest bang for the buck to do with the mini-cats from Bigdaddys and leave the nice, factory exhaust system intact. Long tube headers would be of no use as far as sound if going catless, and they don't produce any power gains on a stocker or even some 9 sec cars like Lindas, so save your money there..Getting rid of the cats isn't about HP gains as i know that the current cats flow very very well. It's about noise level. The cats remove a few Decibels for the exhaust note and I like my cars to sound loud. My Ideal setup would be like my other cars and truck, long tube headers no cats and twin AtAt 2.5 Aero Turbine mufflers straight out to 5" tips. However I feel this would kill my warranty, so i am gonna hold off for a while
I know how loud it can get. I have included a pic of the exhaust systems on my other cars and truck. Like you said it can wake the dead.
