ok so i installed my bov, Sounds awsome, as well i can feel the turbo spool maintin its speed quite nicley, hwoever the car used to back fire and what not, you all know how it works... heavy throttle let off as the rpms drop boom,... hahaha i love it, but since i installed the bov it bloody well sounds like a shotgun BOOOM, people drop to the ground or cover there heads! its hilarious. is this becasue of the new bov not recirculating the air??
thanks,

oh, S5 turbo, 2.5" str8 pipe, no emisions, no power steering, premix, blitz bov.
15000 miles on fresh engine.

 

Yes.

 

have you noticed the bright flame out the back (at night time)? LOL

it freaked me out for a while, but I got used to it

 

yeah. I installed a 3" full back straight allt he way, first time I took it out for a spin, got the crap scared out of my when I saw the housed around me glow orange every time I took my foot off the gas

 

Adjust your TPS correctly.
The car isn't supposed to do that.

will it damage it? i never knew that. looks like i got some work to do this weekend. thanks ted

 

You might hurt your mufflers.

Yeah, if the TPS is off, then the ECU doesn't know to go into decel fuel-cut.
See, then the TPS tells the ECU that the throttle is all the way shut, it goes into a decel fuel-cut.
It's supposed to turn the fuel injectors off when you lift off.
If the TPS is not adjusted right, the TPS does not tell the ECU that the throttle plates are all the way closed, and it keeps injecting fuel into the engine.
KA-BOOM.
It might be novel, but it gets annoying after a while. :P

My car with the GReddy Type-S kit has never backfired on throttle lift.
I do adjust my TPS quite regularly though.
