Directly from my tuner to you
Making power safely should be paramount for anyone tuning their vehicle. The following post was made today by the person tuning my vehicle and thousands of others around the planet.
"Any Power Adder / Forced Induction, Turbocharged, Supercharged, or Nitrous vehicle at WOT needs to be in the 11's for AF. Experienced tuners use 11.5 to 11.7 as optimal safe air fuel ratios. Higher A/F ratios will net more power however it isnt set up for vehicle longevity. Lower A/Fs (richer) will be less power however safer. We really do not want to see mid 12's or higher at wot. This is all about heat. With heat also comes a propensity for detonation. Not every cylinder is burning at the same exact a/f so when you are measuring at lets say on a dyno know that its a collective measurement. So actually you will maybe have some spots leaner in some cyls and / or a difference from bank to bank. In an Ecoboost most pistons are a cast piston so this is even more important. They are not as strong as forged pistons which are way more durable and resilient. Cast pistons are much more brittle and more prone to cracking, losing rings lands, and skirt breakage. This is why we use a collective lower target number to give us headroom for responsible tuning. Safety and vehicle longevity comes first.
Any NA vehicle we usually will take it anywhere from mid 12's to low 13's for maximum safe power depending upon where the vehicle likes it. Heat is heat however you can get away with a whole lot more NA than you can in forced induction application.
In a vehicle tuned mid 12's or higher with forced induction you are slowly chipping away at its life expectancy. This is fact. We dont want to have everything so close to the edge that a sticky or slightly clogged injector, fuel pump issues, or bank to bank inconsistencies contribute to your down fall. This is why we use Max Safe power tuning guidelines.
I hope this helps. Knowledge is Power!"

PM me
If you want to talk directly to the tuner, PM me. He works over the phone and email. Answers any and all of your questions. Been with them 4 years now and never had an issue.

Hello violinguy77, If I remember right I have been with Ssi almost as long as you and our trucks are identical. I have experienced the same thing as you and will be upgrading to the newest 93 performance soon.

Great position for a tuner to have. It has always been talked about in the Lightning community that optimum air fuel ratio is 11.7. A whole bunch of knowledge that is being used on the new trucks was learned on the backs of Lightings/Cobras in early 2000's. It is a great time for a horsepower junkie like me to be alive......Enjoy.
