k/n filter, ond open exhaust(no muffler or cat, just straight pipe for the test) i do beleive i had 60k on the truck at that time. that was several years ago. now i have 180k miles and prob a third less power. she is getting tired. i forgot i also bypassed the temp sensor to make the computer think it was below 32 degrees. it dumps more fuel in and makes more hp.
i know this sounds really basic, but can someone explain that dyno sheet, i dont get why there is 4 different lines, which one is hp and tq. he said i had 181 hp but the line thats closest to 181 is flat, wouldnt the J curve (downshift) one be HP?? that one goes to like 190's
