That has its true merits, but curious if performance is given up?

I also swithched from a shimmed WG to Tial and am very happy- it made a noticeable improvement. The shimmed one bled off to 12-13 at redline and the Tial holds 15 easily. I'll post a Dyno comparison within the next few weeks.
Lart, why is the Tial chart so choppy and the previous one smooth? My original was choppy and I was hoping the Tial would smooth it out. https://rennlist.com/forums/showthre...highlight=dyno

that was my initial run, I had to do some tuning after that, this is one of my latest charts

Ahh, very nice. Not sure I'll have the ***** to turn mine up to 21 though. Then again I didn't think I would turn it up to 18 either, but nothing bad has happened yet..

I sooo wish I had done a dyno run back before I tore the car apart.

I'll add a little here...
I have one of Danno's Wastegates - kind of...
When I was going through my financial "adventure" with him, I'd had enough, and told him I was returning everything - chips, FPR, WG (I had already installed the HG) - but before I did, I opened the wastegate. It didn't have a washer or shim - it had an extra spring inside.
My old one was actually in better shape than his rebuild, so I cleaned/rebuilt it, added a similar sized spring. I figured it was worth a try.
It did hold boost better - I saw a solid consistent 18 psi (as set on my EBC) at 5800 RPM. Problem is I think a 22 year old WG will still not be ideal. It does stick at times, causing uneven boost, but for $1.00 in parts I can't complain.
I have a 38mm TiAL on order from SFR. Looking forward to newer technology.
