One more thing, this may not be the "main issue" but I read on another thread about using platinium plugs in our SC motors was not a good thing. When Kenny Brown installed mine, they did replace them with copper plugs for that same reason. Thinking about it, it may have been you that I had mentioned this to previously, but then again I'm on 5 different medications so I maybe dreaming.

Good Luck!

 

So what kind of computer readings would I be looking for? I can have a diagnostic done tomorrow, but I need to know what to look for in the results...

Anyone who can tell me what to look for, please reply as soon as you can.

Thanks a million

 

For a more accurate horsepower reading, run your truck across a scale to get a better weight number. A lot of scales have a dial or digital readout so you can run across them after hours to get a good estimate without paying for the decimal point accuracy.

A point about the g-tech. It starts it's readings as soon as you start moving whereas at the track you get a little rolling start. If you are spinning the tires off the line, then this will hurt your numbers.
