A change in my order
 

I sent Corey an e-mail asking her if an 87 octane performance tune would be a big difference from a 93 octane performance tune with my mods which consist of: Air Force 1 CAI, Aero Turbine 3030 SI/DO exhaust, 3" leveling kit. I also wanted my tune to replace slot one (the tranny only setting).

So my question is really how different will the 93 custom tune be from the 87 custom tune?

thanks,
Jon

I had this same question when I placed my order i have the 4.6 with 3in leveling kit si/so borla exhaust and gotts mod intake...I asked Corey to ask the mad doc if the extra MPG or HP i would get between the custom 93 and custom 87 is worth the 30 cents more per gal of gas and she said he said NO :)...I had already put on my order form i wanted a 93 custom tune and also a 87 custom tune. She could have just taken my money and been done with it but she let me know the 87 custom tune was great for MY MODS and i had no need for the 93 custom really(talk about customer service:gryphon:). However like I said this was for MY application only and for what i use the truck for.

There's about a 10-12 HP difference between the two programs at mid to upper RPMs. For daily driving there's little, if any difference. It all depends on what you are looking to accomplish with the vehicle. If maximum high RPM performance is your goal, then a custom 91 or 93 octane performance program would be the ticket. If you are looking to make your drive to work a little more fun or just want to pick up a little fuel economy, then I don't think it's worth the expense for either the calibration or the fuel.

Hope this helps.

Bill and Corey,

Thanks for the input. I'm again assuming you haven't gotten to my order yet and if possible I'd like to change the 93 octane custom tune to an 87 octane tune.

thanks,
Jon

I'd also like to have it replace the tranny only setting on the gryphon as well if you don't mind.

thanks again,

Jon

Jon, I'd put the last two posts in an email or a PM to Corey if you want to make sure she gets them. Make sure it includes your name and address so they can find your order.

There's a lot of stuff flying around on the forum, your requests could easily get lost in the flurry.

Take care.
