Whilst looking for some performance chips I came across these two websites. I have no idea if these would work but anything that says 20hp increase for $25 instantly makes me nervous.
Considering Predeator or likewise. Any recomendations would be greatly appreciated.

If anybody knows if the race module could/does work then please let us know. Wish the website showed install point so I had an idea.

 

If this really worked as well as they claim, more people would be using it. I wouldnt waste my time with it. The fact is, tuners need to be custom tuned for each modification, let alone each vehicle. There's no way a generic tune could 'magically' add that much HP to any vehicle it's attached to. I'd go with your Predator (I'm looking at Xcal 2).

 

Looking at Xcal 2 also. Problem is I know almost nothing about them. Thats why looking for advice. Any reason Xcal 2?

 

There's no specific reason, and I havent even decided on the X-Cal yet; I'm am leaning towards it though. The main reason I am headed in that direction is the customer support with the X-cal. I have heard of a number of helpful Tuner guys who have been successful in helping customers with their X-cal. I havent heard of anyone who does good Predator tunes and I dont want to blindly pick someone who sucks, because it's a big investment. That's basically it right now. If you do pick obe, let me know what you think of it. Im planning to get one in the next month or two.

 

all it probabally does is 'pretend' that all air comming in is cold, it could be 120 degree air going in and the computer will thing that it's more like 60 degrees. It's terrible for any engine to do that. After 5 years, your engine will blow...

 

Or it probably intercepts the signal on mass-air equipped vehicles and modifys the signal output. That'd be the easiest way.

 

it probably did work just for the one vehicle they tested. and if the parameters arent the same or they used different dynos any car could make horsepower. heck you could change your windshield wipers and then put your car on the dyno with the car hot and say they caused you to lose 20 HP so dont buy those wipers! HAHA usually if it sounds too good to be true it is
