i'm on the system that after you get 500 miles on it, giv'r hell.

 

just washed her real good so that should yeld me 5 more rwhp!

Question: Tomorrow has scatterd showers in the forecast, will this - or + effect my dyno?

 

That should lower the barometric pressure as the front passes through, the lower pressure would realte to higher altitudes but the lower temps should produce higher numbers as a result of denser air. But then again, the dyno operator should correct the numbers. So then you will be on a level playing field with dyno's across the country.

 

when yiur buying a truck with like 5 or 10 miles brand if you floor it is it bad for the motor or what? i tryd out a 04 yukon with o miles and was pretty slow

 

Well my approx. 750 mile oil/filter is done (Switching to Mobil 1 at 1500 miles).

All set for tomorrow!

 

I am anxious to see what it pulls. My last time to the dyno was with a new motor. I had an appt to dyno tune on a Saturday and I didnt get it running til Friday. I put about 100 miles on it just to check for leaks,etc then I made the 220 mile trip to the dyno so it had just over 300 miles when it got strapped down.

 

just getting ready to leave I'll be checking in later
