a few weeks ago i ran 15.13, with a baisically stock car , with a temperature of 74* F and 3/8 tank of gas... (In Denver, CO- Alt. 5800 ft. (14.03 at sea level))

sicne then i installed a 160*stat, short throw shifter AND K&N FIPK....

yesterday i ran 5 times!!!! at a temperature of 65 and 3/4 tank of gas..... 15.21, 15.13, 15.16, 15.19, 15.16,

So much for the $200 for the k&n!!!!!!! rediculous

does anyone have any ideas of what coulda went wrong

 

Well i don't think the k&n will do to much on its own. But I think it will help make all your other mods a little better.

 

so whats next for me??? MAF? Elbow? Headers?

confused on where to take my next step....

 

Well i don't know how much i will be because i'm just getting into modding lt1 myself. I'm used to turbo cars. But i would say headers would be the next step. Then maybe elbow. But for the best gain i would say headers. But your emission laws plays a big role in this. Or i should say if you want to abide by them or not. Also i noticed that you have the slp loudmouth system on your car. I've heard that putting headers and removing you cat will make your car sound bad with the LM. I can't tell you for sure because i never heard the system myself. But you may want to think about that before you think about headers and stuff.
