How much WHP from 10% Lower on a Redeye? Forza Stage 2 Build Started!

Hey Gents,

So I ordered my Hellcat Redeye Charger last year and had the dealer install 3.09 Gears and Nittos - which compared to my old 707hp Hellcat with 2.62s...was definitely noticably faster.

However, regardless of what I had read on many threads, the 3.09 gears (when installed without a tune) create issues with the cars match-revving during downshifts and other small quirks with shifting.

So, I've decided to bite the bullet and get the tuned. While I'm at it, I'm doing a mild build.

The car will be receiving

  • ATI 10% OD Damper
  • ER14S plugs
  • Mashimoto 180 Degree Thermostat
  • Forza Tuned Stage 2 Tune- and TCM tune.
  • Gates Belt


Please spare me the time starting a discussion about voided warranties - as I don't give a shit- financially its not a worry and regardless - I'm sure the motor/trans can handle it just fine.

My questions -

Is anyone running a 10% lower on a Redeye? What type of boost should I expect? RWHP numbers? 1/4 Time on 18'' Mickey Thompson ET-Rs?

I thought Forza did lots of real high end cars, exotic euro stuff too. I mean, every shop I called prior to where I sent mine was a year out. I dunno, just htought I would chime in. Forza would not even talk to me about tuning my car before I sent it in for the 426 stuff. But, thats what name recognition does for you as a shop owner right? Makes it so you can pick and choose clients, take your time, or... just say no.

Not sure.

Every time I’ve been in Brenton’s shops there have been McClarens, Lambos, Ferraris, Vipers , Porsches…you name it .
Waitlist year and a half?? Yeah I dont know about that. And if that is true, hes running that business into the ground. Nobody is waiting 18 months for boltons. There are far too many other shops around that can do this work at this level and do it quickly and probably cheaper.
Having an 18 month backlog does not automatically indicate running a business into the ground. There is a limited amount of facility space and quality labor…and willingness to continue to grow the business. The owner may be stuck in a lease or is unwilling to expand capacity…just ads to stress and working hours for the owner.

Recently a client was upset my firm had a backlog for tax compliance work. My response was I cannot predict when extension clients will provide their documents, so the backlog was out of my control…it happens when too many clients decide to mail their tax package in quick succession. However, I wanted to ask if she gets upset if she ever encounters a line anywhere else in life?

Just playing devils advocate, but I have no experience with Forza…their videos do show a great attention to detail.
