i went to dsr today to get tuned with poor results. after doing a leak down test, i had a 3% 12% 12% and a 7%. but when i do a compression test, i get high 190's all across. this is on a 84mm 9-5-1 motor. what does it mean when you have good comp numbers with poor leak down tests. my tuner said it might be the rings still trying to seat. the motor has 650 miles on it right now. the highest dyno run was a 170 whp. this is with a revhard 2c kit. anyone have any awnsers???

Your leak down results are okay - Your still in breakin your motor. But, it sounds like DSR - HAVE NO CLUE TO WHAT THEY ARE DOING.. I leak down is not accurate for testing piston ring. A leak down is more accurate for testing bend valve.
