Hi

It's been a while and I hope everybody is allright ! So I was working with my brother on the Marauder and we finished rebuilding the entire engine and putting the Whipple with everything together (Thanks to you gents and this awesome forum).

However, When we crank it for the first time we notice the RPM Is always High (Like 4000 rpm+) The throttle position is close ! But the RPM Is not getting any less than that !
I tried and checked the Whipple bypass actuator Valve and its functioning OK. And it's getting lower a bit only if I disconnect ALL The whipple vacuum lines !

So my question, Is this normal since the car need to be programmed first before cranking ?

Need your help gentlemen, As I'm sure I'm going to face issues in start-up ! But I have big faith in you gentlemen !

I well post pics soon.

you have a vacuum leak after the throttle body, say..... intake manifold gasket? blower to intake gasket?

Is the IAC mounted backwards?
