I just installed my HFC's today, no check engine light, I went onto the freeway tonight, and I smashed on the gas to see how the car will do. I went from around 45mph to 80mph... and the car hit the speed quick, but there was a huge lag and loss of power between shifts, sort of like gas/air was cut out of it, after it hit the next gear it continued with it's power.

I was wondering if anyone experienced this. NO CEL's... I want to know if I hit the rev limiter or if it was something else that I should be concerned with. I wasn't using the steptronic.

 

I've never experienced that in auto mode, only in tiptronic when i misshift and hit the limiter. Try using tiptronic and shift and 7300 and see if you have that problem. If its gone then its no biggie cause people dont' usually redline gears in auto as often as tiptronic.

 

even if I haven't reflashed it?

It felt like a gas cutoff. I didn't like it at all, it got me all worried. I'll try it tomorrow and see what happens.

 

I'm not sure what my car felt like exactly because i got my valvebody quite some time ago but from what i remember i never got a "gas cutoff" in auto mode, only in tip when i shifted too late. Just see how it goes toamrrow and post some sounds clips with your new HFC

 

I'll try to get some clips in soon. it's pretty loud, but I think that has to do with the fact that the gaskets aren't fully sealed up and the condensation that gets into the exhaust from being open. Atleast there's no rasp.

 

ive hit this while at the track in 1st gear... i doesnt seem like it will hurt much of anything though its very soft on my car and there is just a delay between gears
