Lots of talk about this predator.
I also ordered one myself.
I have no mods, just few things like mentioned in my signature.
Many things I can not really grasp as I am no mechanic .
So simply asked : are there some things I should NOT do when I get my predator in or should all be cool?

Just stay away from the custom setting section - especially where you can adjust air / fuel mix and spark (timing advance).

Here's some of what PPP has been doing for me. My car has Stage II heads, and a Track Warrior XL cam on a 6.1L with stock headers and cats, and Corsa cat back.

I'm loving the car, it's awesome to drive!!!

Same tune, different dyno days.





Next tune, compared to first.





Another tune compared to first.

We're not done yet.... Haven't touched the spark, and there's no knock retard.

jaak,
That's very nice of you to post all the various results of your tuning. The graphs look great and obviously promising to those who are using or plan to purchase the Predator.

(Too bad I have no idea how to read/understand them...I'm technically challenged, though!)

Thanks for your helpful post.

Hey Jaak i have the same heads and cam as you... im going this friday to have my car dynoed... ill keep u guys updated

Hey guys, just a heads up I went to ProMotion Tuning and was the 1st inline to get my car tunes with the full software.

Here is the link to what went down - http://www.300cforums.com/forums/per...o-results.html

I didnt expect to get a ton more than what I had got with my +5 +5 -5 +4 +2 +2 modified tune, but we nailed down AF, reduced the Knock retard and tweaked a few things in the middle.

Now that they have had some time to tinker more, I have 2 new tunes to play with that should fix a few small things you see in my dynos.

Tip in Spark and some TM issues.

I hope you enjoy

I finally got my car dynoed today... here are my results... numbers are low it was the only first tune loaded and we did 3 runs,.... hp slowy decreased but torque kept rising so thats a good thing... im going to see if ppp can make the tune finer if possible and run it again.

wow, thats ugly. I am going to address the obvious KR going on at 5500rpm. You asked me earlier what KR is and now you know, lol. That big drop in power is Knock Retard and is killing your upper rpm power, but it is an easy fix.
