Dyno tune now or wait until summre blen gas? I am just finishing up my stock lq9 with custom EPS cam build and am debating if I should have it dyno tuned now or wait until the winter blend gas goes away????? The car is only a toy and will basically be driven spring-fall. Only bad thing is that it looks like winter gas does not go away until May-ish.
I don't care about 5 hp, just want to make sure it won't cause me any issues.
thanks!

that shouldnt cause any noticble issue. The bigger issue than additives will be octaine ratings ( if you tune with 93 but use 87 afterwards) or if you tune your car in 35 degree weather, but drive it mainly in 90 degree weather.
Your MAF will try and fix the temperture swings. If you go speed density, obviously your MAF cant help with the large temperture swings.
when tuning the car you may not get any knock in 35 degrees, but in summer heat traffic, you can be all over the map.
