does anyone know why the car at around 5-7 rpm lags... It jolts and loses power. starts lagging really bad. have a vafc in there too. but can't figure it out.. if anyone could help..

thanks

 

I figure its a jacked up install. j/k G.

 

dont hate

 

I'm not sure if it's same problem but when I shift fast at 9K rpm on 1-2, 2-3, & 3-4, RPM will hold at around 7K for about .5 seconds and car will start accelerate again.

I believe that it was due to stock clutch I have.

 

yeah yeah thats the problem.... why do you think its the clutch?? I have heard that it was cause the car is not getting enough fuel.

 

I have a vortech kit on my car, it has been 1 full week, I haven't experienced this problem at all. The car feels like it is ramping up at 4K and pulls all the way through to 9K. Does your belt have enough tension?

My buddy also has a vortech kit, he has a problem with his clutch not being able to handle the power at 9K shifts. He engages the clutch and there is a slight delay when it grabs.
