Antone, it looks like you keep asking the same question, but in different threads. What mods have you made? The way the canned tunes that come with the predator are set up is to add timing in the base tune for example 91 Octane Tune adds some degree of timing what the amount of is I do not know. The 91 Octane CAI tune adds timing and fuel. So each canned tune adds alittle more timing and or fuel. It will depend on the type of mods, provided they are mild mods. If you install headers, high flow cats and maybe a cam and possibly new heads then that is when you would want to see a CMR Tuner that can dial the car in. Also with the predator you have the ability to adjust different parameters ie; Fuel @ WOT and Timing @ WOT. The key is to log the parameters and use the best gas availible to get the best performance. Just changing the thermostat out can help alot and the exhaust w/CAI. Firm up the shifts.
One other thing is to search the forums ie LXforums, charger and magnum to name a few for the answers and opinions of others and you can get an understanding of the capabilities the predator and different mods that can be made.

Thanks for responding, yes i am new to all this im not a gear head at all, i just started learning the basics. I have changed out my
exhaust added duals from the muffler back. I added a K&N air intake and installed the 89 predator tune. i GUESS WHAT I AM ASKING IS WHAT ELSE CAN I DO WITH THE PREDATOR or what else is there that can be done. If that makes any sense. I would love to get a response from the predator guys. And if possible can i send them my specs and maybe they can make some mods...i dont know

You should be just fine running the canned tunes.
Modifying any further should be done with a wideband or on a dyno...

Thanks

Ok, when you say canned tune what is that exactly ?

[mikel]

The tunes that came in the Predator.

[antone302]

[mikel]

do you have 22s on your car or are you try to fool the computer to think you have taller tires so it makes your car seem like you have a bigger gear
thanks

Unless they actaully are taller, changing the computer setting won't do anything except throw off the speedo and odometer. Anyway, shorter tires give a bigger rear end ratio, not taller.

thats what i meant if he had the 17s on but used the predator to lie and said he had 22s you no what i mean lol

[antone302]

uh....the car has 22s on it

[Mike_Levy]

Wouldn't matter. UNless the actual diameter and circumference of the wheel/tire combo was different then stock, no changes need to be made. Obviously when going from 17's to 22's you went to a lower profile tire. That keeps the total size almost, if not, identical.
