Whenever I make a eng mod I test my 40-60 mph times to see what the impact was. I have a 1996 GBM with a 454 TBI that weighs about 15,500 lbs Stock when I got it was 22 secs. General tuneup brought it down to 19 secs. Headers, FF muffler, and a CAI brought it down to 14 secs. Advancing the timing from 4 degrees BTC to 9 degrees brought it down to 12 secs. Stock HP was 230 at 1800 rpms not sure what it is now maybe 300 hp.
