Thought of the day.

I need a time machine

I share Trevor’s concerns on consistency requirement and always following the same recipe.

Some techs say it is hard on injectors, including Ford trained dealer techs.

But I can share a personal experience with my 06 last time I had it tuned.

I towed it to Dasilva’s.
Filled up with 91 octane from Shell along TCH up here before leaving.
Place very busy and sells lots of gas so supply always fresh.

Laid down good numbers on dyno.
When all was done, Matt Dasilva asked me if I was curious as to what a 93 tune would give me compared to the 91.

They sell similar race fuel additive octane boost at the shop and assured me it was safe to use.
I agreed to try out of curiosity.
So he poured some additive in the tank and did his thing on the laptop and did another pull.

The result was only 2 extra hp over the 91 tune.

Matt told me I had very good gasoline and to keep using it, and not to bother with the additive.
In my case, it was not worth it.
And, I feel better driving that combo.
I’m not afraid of detonating a piston.

Another thing, the Irving refinery in St-John is one of the most modern in the country.
And Irving keeps the best gas for its own flagship stations.
So if you have access to a busy, high volume Irving station near you, consider filing up with that before you ship your car, have it tune with that and keep using it after.

Your result might resemble mine.
Not that much gain with the additive.

How long did Matt wait or drive the car around before doing the pull with the booster. What I see there could be a 20 to 40 minute mixing time before it gets to the injectors, if not per mixed and add to make a full/half tank

Never thought of that variable before. ?‍♂️

Direct answer: I don’t remember.
Estimated answer: anywhere from 10 to 20 minutes.
He poured it in, then did some data modifications on his laptop. That took a bit of time.
Then the pull.

Car was not taken off the dyno in between to get driven around.
So no sloshing around in the tank.

But then I reason that if the mixture had not been appropriate, there would have been spark knock (detonation).

Anyway, am not a fan and have not used since. Don’t plan on doing so either.

I like my cars to handle and give me repeatable performance on hot days, IE: at a HPDE on a hot summer day, but am not building race cars.
This is why I like naturally aspirated cars over forced induction.
Boost creates a lot of heat and suffers on hot days.

As you know, we don’t have access to 93 or 94 octane anywhere in our region or eastern Quebec for that matter, so I don’t even think about it.
I prefer the confidence that my engines will hold together over chasing peak numbers.
