Looney Tune Question.

Been running looney for a few days and absolutely love it, and one thing I noticed was when it cranks up, the truck cranks with authority. Sounds like a whole nother animal under the hood. Anyone else noticed it compared to to stock/ other tunes, and is that more fuel demand on start up or what. Doesn't bother me just something I noticed off the bat.

Yep, Vivian's tunes have always had the pissed off start up. Some of Eric's race tunes do the same.

Not trying to hijack here, but what are the big differences between Looney and SRL. I have SRL now and have been thinking about trying the looney out.

SRL power comes on smoother and sooner. Looney is like a switch turning the power on a little higher up.

What he said^^^^*^

Power feels the same when at WOT, it's just the driving characteristics that are noticeable.

No tune should feel like a switch when the power comes on. Power delivery should be nice and linear. My Looney does not feel like a switch at all. Talk to Vivian about it and she will correct it. Mail order tunes are rarely perfect on the first try and take several refining iterations. The more feedback you can provide the tuner the better they can tune the truck.

Maybe a light switch was a bad analogy. The power of Looney comes on later and less gradual than the SRL. Feels more like a stock truck until you get farther into the pedal than the SRL. Shifting of the Looney is more comparable to a stock truck too compared to the SRL. SRL has faster, crisper shifts and stays locked a little bit longer in OD. I actually had to get Matt to tweak this b/c it was not downshifting early enough and getting hot and smoking. My Looney would downshift similar to if it was stock tuned (not saying that the trans is left alone, shifts are still firm and crisp on the Looney, just not as much as the SRL). Three quarters to full throttle I'd say the power is equal and behaves just like one another.

To sum it up, SRL is faster and stronger from zero to half throttle than the Looney but both are about the same after 3/4 to full. Looney has more of a 'hit' when the power comes on. Oh, and my Looney smokes more than my SRL.

Hope that explains it a little bit better.
