Tuning for VTA BlowOffs

Post by Sassimac »

Hi There...

I noticed on the main website VT can handle VTA BlowOffs. What needs to be altered in this case?

Thanks..!!

Move your MAF after the BOV and use it in blow-thru mode. You lose accurate IAT info though.

I will look at a tuning solution to that at some point.

I would be also interested for that.
Is there already a tuning solution for VTA BOV?

Long story short, if you want to switch to VTA just do it, just make sure your BPV doesn't leak at all prior to removing the recirc tube and capping the TIP.
