I don't think we'd hit higher boost levels as the ECU probably has a target peak boost. Just maybe at the top end, we'd make a little more power from the free-er flowing exhaust.

As for vacuum regulators, I'm not sure if I'm super lucky or I'm oblivious, but mine has yet to show signs of failure. I'm wondering if they burn out due to heat?

That's true, the aftermarket mid and axle back would definitely allow the turbo to breathe a lot better than mine. Not sure what causes the vacuum regulator to fail since I've seen bone stock cars have issues. I know the symptoms are fluctuating boost and/or a buzzing sound.

Luckily it’s a $90-$100 part, so not too bad.

My newest add-on!

Yea I’ll probably do it in black wrinkle paint, that way it matches the charge pipe. Throttle feels a bit more responsive and I’m sure the air flow has been improved.

And Looks good man. The breaking traction in 2nd looks impressive. Lets get some better videos if possible. attach go pro to the outside looking at the back wheel. would be nice to see an outside perspective

also can we see a full brake torque type launch? bothers me to no end to see that still dreadful lag at the beginning. i know even stock the car is capable of a pretty strong launch when brake torqued. interested in seeing one tuned doing a full launch

And sheddy just curious what's the retail so far for all the parts you purchased + tune + install. everything total to date? So people have an idea what it takes to get to your point if they're considering a 200T.

AND

does anyone with a stock 350 want to roll-race sheddy (on a track) i would love to see how it compares. just a two gear pull from a roll. mid 2nd to top of 3rd or whatever.

Lol I already gave the stage 0 dyno to matt but he apparently didn’t want to post it. He requested to wait for stage 1-2 before posting which he never got to do.....

OV stage 0 was about the same as TTI Stage two, just a few more ft pds
