my brother and i both had pitbull chips in our trucks. He totaled his ty about 2 months ago and mine still has it. But today i figured out from a member that it is the 138A "Strip" chip not the street. I know that the intercooler comes on alot later than the 137 but what else is differnt. and is it safe to be driving it in a truck with stock everything except for, 3 inch exhaust, cai, and some other little things????


thanks

Re: Important Atr pitbull questions!

The strip chip gives you more timing.
100 min octane needed.
Also probably a little more boost.

The strip chip has slightly more timing then the street chip which means it's slighlty more aggressive requiring higher octane to run safely which is 100 octane where as the street required 93. In my opinion just stay with the street chip and be done with it. Unless you only use 100 grade in you truck and hot wire your ic pump or have an a2a setup.

Neither of the two chips are made to raise your boost levels as they are both 2bar and so can only read and calulate fueling for 14.5lbs of boost safely.

If you want more boost etc then go with a custom chip or a used ultimate and 3 bar sensor

how is it more "agressive", timing wise compared to the street chip?Say if they both were running 100 octane How does more timing make more power over the street chip? and whats the worst case scenario if i use 93 octane?

It advances the timing more than the street chip under boost.The more timing advance you run,the more power you make.To a point.

If you run 2 identical trucks at the same boost level,the one running more timing will make more power,providing it has the octane to do it so it doesn't knock.

How does that work? Beats me,I'm not smart enough to understand,I just know.

Re: Important Atr pitbull questions!

More timing equals more amount of time the "explosion" is pushing down on the cylinder. There is a limit though and I have found it to be around 22 deg advanced.

Octane is a resistance to detonation/ignition. Lower octane fuel ignites faster/easier. If you ignite the mixture too soon, well the crank is trying to spin backwards, or all the forces go directly into the rod/crank/bearings and not into the motion we are wanting.

Higher octane gas requires more timing to get going -vs- pump gas. Put c16 into a stock chip truck and it just might slow down because of this.
