What are you guys reading for vac at idle?
Also I get a little bucking in first gear sometimes any ideas?
the car:
Comptech w/cooler.
FMU
440 injectors.
Comptech header.
T1R test pipe.
Apexi exhaust.
HKS bov.
Clutchmasters st. 4 and flywheel.
Thanks.

 

Do you have an EMS for the 440s?

 

Have the Comptech ESM.
Also a VAFC 2 that is hooked up but not running anything.
When it was dyno tuned apparently it didnt like
the VAFC and the Comptech unit together (this is what i was told)
I was planning on pulling the VAFC alltogether and eliminating it from
the system.

 

Vortech at idle, mine reads about 10 to 12 psi vacuum.

Your "bucking" is a function of your clutch control and has little to do with any fault of the car.

 

I have about 20-25 at idle.
more of a stutter than a buck as I
have stated above. Pretty sure not clutch related.

 

Your vac at idle seems a bit high compared to mine. Maybe just a difference in gauges.

Not sure what you mean by "stutter", but "bucking" on this car is a well known phenomenon that can be bypassed with a little foot work:

Thanks Xviper.
I read the other posts with the bucking thing..
This is my situation, so thanks for the links. I didnt even search
for the problem. I assumed that it had something to do with the vacuum.
Apparently the old saying about assuming holds true.
