Looking to find the simplest and most reliable way to make some extra power.... nothing extravagant.
1. What can be expected from just using the DSP without any changes?
~increased boost to 19 psi spike and 15psi hold and a afr of about 11.9. every car is different so these numbers can vary do to things like wear and tear on parts and or boost leaks etc.
2. What is the next step after the DSP? WGA? Wideband?
~once you get a predator your now going beyond your average bolt ons, ur in the tuning part and reliable monitoring gauges are a must yes get a wideband to monitor air fuel ratios.
3. What is the benefit of the WGA?
~stock wga is fine though the word is the foward motion wga (fm wga) is better for pcm controlled load response but try your stocker 1st if you feel you dont like it change it i guess.
4. What is the benefit of the wideband? Does it work in conjunction with the DSP? How does this connect to the car?
~benefit of the wideband is you can watch your air fuel ratios make sure your car is not running too lean nor too rich. wideband will be a separate gauge from the predator it will help you watch your afr's if you want to start to fine tune things incase the can tune from the predator is not doing it for you. the wideband has a sensor that gets installed in your exhaust system before your cat. the predator gets plugged in to your OBDII port and you flash the tune in and then unplug it.
I have built several old school V8 drag cars, but this is my first ever dealing with these new fangled computerized car thingies
Thanks in advance
oh and welcome to the world of computer controled cars and fuel injection
