hey long time no see all,having a problem with my ca. When im driving hard and go to snatch a gear it feels like its goin ultra lean. pretty much ever i try to bang a gear it falls on its face immediately, it doesnt have a problem other wise pulls to redline fine just when i bang gears...its kind of irritating.thnks chris.

Like, what exactly do you mean? Could you elaborate a bit? You mean it falls out of the powerband or what?

lol its kind hard to explain.Okay lets say im doing a pull on the highway, ill stretch out 3rd and then try to snatch 4th gear, right as i put load on the engine going into 4th gear it falls on its face instantly. Even from first to second, second to third does the same thing. forth to fifth it does it too.

It never breaks up pulling to redline, just seems to be when im high in the revs and come from load to no load to load again. my first instinct would be a TPS but we adjusted it and its all good.

thanks for any help

Thats really weird man, I don't know what to say. Is the ECU throwing any codes? What about if you power shift the thing? Is it only when you let off the gas entirely to shift that it falls on its face? How is your waste gate hooked up?

You have to be venting your BOV to ATM and not recircing like you should be.

Yeah but my BOV has never once been recirc'd in the 6 years I have had my car and it has never done that.
