Has anyone used a ECM tune from Predator Performance??

 

Not that I'm aware, their prices are a little ridiculous IMO. I'd be curious though, I've had the raptorq in my bookmarkes forever!

 

Yeah I agree with you on the price, but it's the only one I can find that gives you 64 hp so they say. I'm hoping I can find someone that has used them and can give me details.

 

Sometime this summer I'll get mine done.

Had mine done in January. Garret is a great guy to deal with.
Now my H2 has 35" tires, a cold air intake, 160 degree stat, shorty headers and stock exhaust with a Magnaflow muffler in place of the stock one. Make sure you give them all your mods, vin # and tire size and such.

After I installed it, which takes 5 minutes, she fired right up, no check engine light, no issues. Improvements, idles smoother than ever, shift points are moved way up in the rpm band, it actually holds a gear until you are ready for it to up shift. MPG... maybe a little improvement there. For some reason I get better mileage on the highway driving it harder than cruise and taking it easy? MPG is about 11.6 to 12, calculated between fill up's.

Power wise, noticed vary little improvement, it is peppier off the line and does take off like a bullet over 3000 rpm (think that is where the real gains are). The big difference was the 160 degree t-stat that woke the bottom end up the best (and no I do not want to get in a thermostat debate).

So is it worth the money, for me Yes, for anyone else that is up to you.

 

Thank you Throttle,that helps a lot. The guy I have been dealing with is Alek, seems to be very knowledgeable.

 

No worries, hope it helps. I think Alek is Garret's brother. Both great guys.
It is alot of money to lay out, just make sure you let them know what you want in detail and they can burn it in.

Good luck and let us know how it turns out.
