Hypertek

ever since i did the tb mod *ported, shaved, removed butterflies and filled holes* a few years ago, car takes awhile to start.. cant think if i missed anything.. just thought that might have been consequences of the mod. I also threw in a rtek 1.5 in as well btw but that has nothing to do with it..

Im aware of leaky injectors could cause this that would be on my list as last resort.

If you removed the thermowax the throttle is going to be closed while starting versus having it cracked slightly. Try starting it with your foot on the gas a little.

hmm thats probably it huh. ok yeah this morning i lightly stepped on the throttle to start and it fired right up.

if you have an rtek 2.1 on the s4 you can adjust the cranking fuel map and it should start easier without having the throttle cracked

Or have a fuel cut switch.
