Which tune 2 or 2.5

in CK Stinger 3.3T(2018+)

I'm about to purchase my lap3 ecu. Undecided on which tune.

My mod list is basically all bolt ones including wmi.

I will be mainly running e30-e40 (wmi when needed) mix will that be enough for 2.5 tune?

My main concern is if I take my car on a road trip to pick up daughter from college and wanted to run 91 would that cause any issues if I wot it a few times?

It usually takes about 3-4 weeks from the order date.

I'm ready to order my E.C.U, but I am curious if it's a custom tune or a CAN tune? Also I have cold air intakes and bigger intercooler and transmission cooler, Borla exhaust system and Hkl M45IL plugs, oil catch can, 2 into 1 Tial .B.O.V. So I'm assuming Stage 2.0? I appreciate the help.

All of our tune is made based on custom tuning countless cars on the dyno. Our LAP3 ECU Tune is superior over any custom dyno tunes or canned tunes on the market. The stage is based on what octane you plan on running. If you plan on running 93 octane or higher, then Stage1.5 would be what you need. Stage 2 tune requires 95+ octane as minimum, and that can be achieved by mixing 4gal of E85+93 fill up. If you add a Meth injection system system on top of 93 fuel, it will make well over 95 octane.

95+. I'll be getting the stage 2. I keep trying to check out, but it wont let me. I do not have a pay pal nor do I want one. I have discover card tho. I'm trying to give you $2300 and it wont let me. The check out page really isnt that great

Hi Paul, If you plan on running 93+E85 mix+WMI, Stage2.5 ECU's max potential will be reached. If your base fuel is 91, adding E85+WMI, we suggest Stage2. Going wide open throttle with the octane fuel lower than the requirement, then you may experience knock & misfire. So it is important to make sure you have the required fuel for the tune. If you stay out of heavy throttle/boosting, it is fine until you get the fuel you need.
