Impressive considering you are running 20's. WHat kinda dyno and what kinda corrections?

 

nice numbers

 

it was dynojet..corrections? so these are good numbers? i really dont know much about stock power vs my mods..

 

what year and transmission?

 

03 auto

 

cool

 

What's the numbers anyway for stock? Just curious.

 

isn't 03 around ~260hp? If so, it would be close to 220rwhp taking out a little extra for the trans.
I have seen all kinds of numbers depending on the car, conditions, and dyno.

I put down a best of 212rwhp with just ztube and filter on a mustang dyno.
Mine is 03 sedan-auto. Dyno jets usually dyno about 10-15 hp more.

I think the difference is that the dyno jet is a free rolling spindle and the mustang dyno simulates road resistance.

 

thats great then. ive got the 05 auto and i put down 225 rwhp stock. with injen cai, injen td ses and crawford plenum i only gained 11 rwhp.

 

do you have your dyno sheets, it will say what correction, that is pretty high for an auto with no ecu for tuning, especially with 20s but these ECUs do some weird stuff and if you catch them on the right day with the right weather, you can get some good numbers...

 

yes sir i do have the dyno sheets right here,i need t find a decent came so i can show you guys,and whats even weirder is..after i was done..when i got the car back the "slip" light "abs" light and "vdc" light were on,and i asked the guy about it he said that was normal that they come on,and they would go off when i drive..well i pulled out of the shop and to my surprise 10 sec later literally they went off..now get this..i drove straight home..i took the car back out at night,and the car felt unbelievable..way smoother and faster i really don't get it..help me out here guys if you know what went on..,im thinking..i remember everyone saying its best to reset the ecu after every mod,i never did.do you think after the dyno when all those lights came on it reset it self and recognized the mods? cause i can tell you i have no doubt in my mind the car feels way faster from earlier..even my girlfriend was freaking cause i was like this car feels different,and i nailed it on a a straight away. and i was blown away of how much faster it was,and she agreed something was going on as well..so please let me know guys if you think what might have happend

 

they dyno definitely didnt reset the ecu, it is probably in your head cause you saw that those are pretty good numbers for what you have and that it felt faster..



did your dyno graph spike up right at the end when the guy let off the throttle, it will give a false high reading sometimes.

post your graphs though when you can

 

theirs no spike in the dyno graph at all

 

here are the numbers
