You're going to have to tune if you want the maximum benefit from a PTB.
TRUE, But it was still worth it for me. The improvement in throttle feel and getting rid of that dead spot was awesome.
Thanks for the detailed writeup. I hope the dyno owner gave you a little price break for the 4 hrs of dyno time.

He did a little, but i understand he has a business to run also.

The increase in HP at any point along the curve was negligible, the most I ever saw was 7 I believe. The tangible benefit is a sharper throttle response at part and mid throttle. That was my experience with a ported TB on my 2005 GTO and again when I added the TM TB to my ZE.

Yes, i fell like a tune with a ported TB will net more power than a tune with a stock TB because of the air flow in crease we saw over stock with the Soler unit.

Soler is still a great option if you are looking for better throttle feel and getting rid of that dead spot just off idle if you are a manual.
