Installed VMAX TB (PICS)
Thanks Norris Motorsports and VMAX for great product.
I just got done putting TB on (took me 10 min) and run car in park for 10 min and no codes or issues.
I plan to take it for spin tonight and tomorrow and see if i feel any difference and how it responds.
hey, porting job looks great and I am sure there is going to be slight more air flow due to great porting/polishing job and hopefully i get 5-10hp as well.
More info how car drives will be posted later.
ENJOY

Great product; you will notice an increase in throttle response right away. I installed mine a few months ago and am very happy with it. You may see a change in idle speed initially. Apparently the computer senses the increase in air flow and enriches the mixture to compensate. I saw an initial drop of about 100 rpm but has adjusted upward after a few hundred miles of driving. I will eventually get it tuned, but haven't so far. Here are my pictures.

I installed mine about a month ago, definately an increase in throttle response, wow! However, I noticed an increase in RPM, but for only about 10 miles or so, then it was back to normal (700 RPM for an UD pulley on mine).

It took 3 weeks to receive TB.
Install 10 min - 4 (10mm bolts) and plug. Very easy!
I just took it for drive.
Notice:
Increase in Throttle response.
No RPM difference - after I installed TB, I let the car run for 10min and at that time it was slightly higher but during drive RPMS remain same.
Can not notice if there is power difference but plan to dyno tune my car soon so we will see what kind of power we see across the board. (No stock numbers)
I like it. Surely worth the money.

I installed mine at the track with these results.
1/4 mile test results DA corrected
2 passes for baseline - 11.92 @ 121.24 & 11.96 @ 121.17
2 passes after install - 11.90 @ 121.18 & 11.90 @ 121.05 (w/o tuning changes)
Most evident as 60' dropped from 1.97 to 1.95 & 1.94

This is ported factory TB
Norris Motorsports in conjunction with VMAX port and polish stock TB.
They send you ported TB and then within day or two you send them your core (stock) TB (to receive 300$ core refund)
At the end, total cost is about 159$ with shipping for ported TB
All their Ported TB are flow tested to make sure they are properly working after port job.
I dont know, to me, it is worth it for 160$
