Please i wanted to know what is the normal reading for our cars at idle ?

I`ve installed MD Spacer and i just wanna check that i dont have a vacuum leaks, i`m using a Vacuum Gauge i just wanna know what is the reading at idle, 1,500 RPM, 2000 RPM and Thanks.

 

if u r N/A i think u dont have any problems. u did the install ??

 

yes NA but i lost 25 whp at the dyno

 

This question may seem silly, but nonetheless . . . Can we assume that your car was tested at the very same dyno shop as previous and that the weather conditions were essentially the same?

 

no and i`ve just noticed something !!!

Fuel tank plays major thing !!

while the fuel tank was near to empty the car was goin too fast, just refilled the tank to full, it seems a little heavier, i dont remember what was my tank at in the first run.

about the weather, no the weather was cooler, in the 1st dyno, the temperature was 70, now its 100 :P, but does all of these thing affect the car to make it lose 25 whp ? BTW both runs in the same dyno.

PLEASE anyone i need to compare my vacuum readings with yours, mine was 23 at idle and 22 at 1,000 RPM. (gonna conform this today also)
