SCT SF3 Tuner help

[trombonedemon]

I'm in Florida and just like any other car, it likes cool and dry air better, it certainly doesn't 'run terribly' or even run bad at all it the hot and humid dog days of summer. On those days it just doesn't have the jump it does on cooler and drier days - but again, it doesn't run terribly...not anywhere near terrible.

Have you been to Arizona? My God, it's waaayy dry. Waaayy hot too, but bone dry. It's a friggin desert dude.

Dyno tuning a stock or nearly stock car for different weather conditions is ridiculous and, as you noted, very expensive. Every pure race cars, not all of the weekend warriors, but true, dedicated race cars do tune around the weather - both engine and chassis. But they are trying to eek out every tiny bit of advantage over the guy in the next lane - when hundreds (if not thousands) of a second matter.

You said your Mustang 'knocks on anything less than 93 octane on a stock tune'? What mods do you have? What year / mileage?

499.00 is for the Live Wire tuner not the dyno cost, you find deals on dynoing a car for waaaay lower then 499.00 and be confident that you won't have to change the tune.

The Ebay cold air, ported throttle body with 2-inch spacer, upper intake and professional products lower intake w/1/2 inch spacer, is what is done to the outside of the car's engine. Humidity is a beast.

Personally I think it is worth having a mostly stock car dynoed because not all stock cars react the same, you can find two brand new stock cars that react completely different.

Just to be sure you and I (and anyone else reading) are on the same page, it's not just the cost of the tuner but also the cost of the dyno time and the guy writing the tune - his time as well. You could quickly spend $800 -850 on dyno tuning a car that has just a couple bolt ons. I did a quick Google search for dyno tuning prices and randomly found the following, which provides a good breakdown of typical rates (courtesy of www.realspeedautomotive.com in Bohemia, NY):

A basic dyno check of a Mustang is $85 for 3 runs with a printout of Horsepower, Torque, Boost (when applicable) and Air/Fuel ratio (tailpipe probe). A/F readings can be taken from the midpipe for an additional $30. A basic dyno check ("Baseline dyno") does not include any tuning.

Dyno Tuning rates are as follows:

Hardware required:
1989-1995 Mustangs require an SCT chip $299 installed (or $45 to remove & access the computer to use an SCT chip you supply).
1996-2004 Mustangs require EITHER an SCT XCalibrator-3 flash tuner $379, or an SCT chip $299 installed (or $45 to R&R the computer to use an SCT chip you supply).
2005-2012 Mustangs require an SCT XCalibrator-3 flash tuner $379.

PACKAGE DEAL: Receive $75 off the price of a dyno tune when you purchase a tuner or chip and a custom dyno tune from us at the same time.

Tuning Rates: Note: Dyno Tuning charges are in addition to the cost of the chip or flash tuner (if required)

Basic "stock Mustang" Dyno Tune: For stock and mostly-stock Mustangs less than 5 years old with modifications limited to ONLY exhaust midpipes & mufflers (no long tube headers), pulleys, gears and "preferred" cold air intakes (Steeda, C&L, and BBK).
