IMO, the unit with smallest margin of error.
Right out of the box it will give the most correct acceleration, braking and G's measurements.
Fact - temperature, air pressure, wind direction, vehicle and individual's driving runs are changable variables - unit's calculation of G's in real time is consistent. It never changes.
To keep your measurements of added parts as accurate as possible, do two runs in opposite direction and calculate the average. Also invest in a digital thermomether with barometer. Try to make your runs with different set up's under the same weather conditions. If you can, run different set up's within minutes of each other. I say if you can, because it is not like header can be pulled in and out like air filter options.
Ohh, one more thing. Adding parts on top of other parts will sometimes hurt performance. Sometimes parts are not made/tested in developments with each other! Keeping a good balance between intake and exaust will do more for performance and driveability than going extreme with one and not the other. Only self variable parts can give you top and and bottom end torque on NA engine. With that said, I can't think of any at the momet! LOL! The smaller the engine the greater the problem -no torque! We are forced to set goals on what we are trying to tune it for. Either good low and mid end torque or top end horsepower.
You are going in right direction! You have the right tools to keep testing! Keep going and you will find what best works for you!
