Default Upgrade from VF35 to TD06H-20G - what to do with the restrictor pill ? Other mods ?

Hello,

I'm upgrading my 207 STI from a stock VF35 to a TD06H-20G. I noticed a restrictor pill on the vacuum hose that comes out of the wastegate, just before the T piece.
What should I do with it ?
Should I keep it there, should i go with a larger restrictor (if so, how large) ? Should I eliminate it ?

Thanks,
Mihai

take it out, you will not need it, and get a new boost solenoid

I went with td06h-20g, fmic, ss headers + uppipe, 780cc, cai, 3" exhaust and downpipe and tune.

the problem is that I'm getting inconsistent boost delivery, going up and down from 17-22 psi in higher gears with this setup.

I'm just trying to get to the bottom of this.

Also it's a lot laggier then my VF35 (I now it should be laggier, but I think not so much), I'm only hitting full boost (20 psi) above 5000 rpm. Do you think the headers are the reason why ?

Overall, in 0-402m drag, my car work better with vf35 and mods + tune then it does now.....

i say go with grimmspeed, great company, and the boost solenoid, and a good tune can fix you fluctuation problems, and help boost come on faster, i say get the boost solenoid and get it installed and tuned for before you start chaging other things

I'm waiting for my new hallman mbc to arrive and get tuned again by Cam, on camtuning.
In that case whould the solenoid be neccesary ?

Also what can I do about the lag ?
The SS equal lenght headers + upipe that I bought from ebay proved to be really strong, not a crack on them for 8 month (despite the talkings here on nasioc), but I feel that they are pulling me down from getting boost more quickly.
What do you think ? Should I go with my stock headers ? Would the loss in top end power will be that noticeble in relation to reduced lag ?

well with the 20g, top end will be nice so i dont think you will notice, but you should be getting the power about 1k sooner, but i dont know if its the headers, with the mbc you dont need a boost solenoid, personly i am not the biggest fan of MBC because you dont have the throttle response of being able to only make so much boost at so much throttle, but i still say get it tuned, and let the tuner see your logs and let him decide, he should be able to tell you whats causing the problem
