On dyno pulls: If I get my stock truck dyno on a cool day (50F) or so, will my horsepower be less on hotter days (say in the 80-90F)?? Also can they adjust my A/F without a chip if it needs to be adjusted from the factor settings??

Thanks in advance for your answers.

yes your numbers will be lower on a hot day and no they cannot adjust your a/f settings without a chip

 

If SAE numbers are used they should be the same however this is only the case with N/A vehicles. The SAE standard does not work for FI vehicles.

 

thanks guys, that's what I was thinking, but me not knowing very much about all this stuff, I had to ask you folks. THANKS AGAIN!!
