do it yourself upgrades

as far as i know, a 7mgte does not require a BOV, as the KVAFM is b4 the turbo, and venting excess boost to the atmosphere would throw off A/F ratio. but im not extremely well versed with GTE's.

if it were running a MAP or MAF system, that would be another story, as those sensors are after the turbo, and can vent to the atmosphere while still receiving the correct air volume signal.

if you get a recirculating system for your BOV, it would be possible to run it, but pretty pointless, as the system is designed to work without one.

someone else more versed with turbo apps can prolly shed more light, but this is my .02.
