After I replaced the MAF sensor about a month ago, i have a feeling that the car got slightly slower again...do these numbers sound right for an 00 SE 5-spd?

0-60 approx 7.3-7.5 sec NOT powershifting (i refuse to powershift)
20-40 using 2nd gear: 2.9 seconds
40-60 using 2nd gear: 3.1 seconds
street start: approx 5-mph - 30MPH idling in 1st gear: 2.7 seconds
If i remember correctly when I gunned it in 1st gear the tires would spin...they dont now although i rotated the tires and now I have michelins on the front instead of the higher performance BFgoodrich. I dont "try" to spin my tires i just used it as a comparison example. feels a little slower on the highway but maybe i just got used to it? i dont know i am confused.

 

How are you measuring your times?

 

using a digital stopwatch

 

your best bet is go to a dyno and get 3 pulls with a/f. it will cost a little but you will be able to see any abnormalities in power and your a/f ratio. the maf is solely respondsible for a/f at WOT so it would tell the real story. no matter how good the watch or your reactions are, the stopwatch is going to be off.

 

what exactly do you mean 3 pulls with a/f? ive never been to a dyno...how much do they cost and anybody know of a good one in new jersey? thanks.
