TRACTUFF VTC LIMITERThe TracTuff VTC Limiter is yet another innovative product that was designed with the average consumer in mind! We wanted to offer a cost effective solution for limiting how much cam advance your motor see's, once clearances have been confirmed, and what we ended up with is undoubtedly the easiest way to limit cam advance. We assume that most K series engine owners own a 50 intake cam gear so it made sense to limit the 50 gear rather than ask

The TracTuff VTC Limiter is yet another innovative product that was designed with the average consumer in mind! We wanted to offer a cost effective solution for limiting how much cam advance your motor see's, once clearances have been confirmed, and what we ended up with... is undoubtedly the easiest way to limit cam advance. 

We assume that most K series engine owners own a 50° intake cam gear... so it made sense to limit the 50° gear rather than ask customers to go through the trouble of finding a 25° TSX gear and have it modified. The process is tedious, as you must find/ buy a 25° RBB gear a, pay to have it shipped, find a capable machine shop to handle the modification, ship it to them, pay them their fee, and ultimately pay for the return freight. Sounds expensive! and not to mention a total headache and a major inconvenience.

Our VTC Limiter is manufactured from precision ground 52100 Bearing Steel and finished to exacting tolerances (+/- .0001") and then heat treated to a hardness of 60-62 Rockwell C. The limiter works by placing the pin in a specific cavity of the VTC gear, where it can float freely, ultimately limiting the amount of advance the motor sees... regardless of what the map/ tune calls for. Please note that it is not needed but if you have any concern with the pin floating freely you may have the pin tacked in place once you have confirmed your engines specific clearances.

No more migraines
I have suffered migraines for years. It was so bad in December 2025 that I begged my neurologist for help. He suggested several things that I was unwilling to try due to the side effects. However, he recommended I try 400 mg daily of Magnesium L Threonate. January 2026, I started the taking it. The first month only 3 migraines for the whole month after years of 3-4 migraines a week. Its May 2026 and I have only had 3 more migraines this year. I highly recommend this product for migraine prevention.

The best Magtein I have tried thus far
I take double the dose because when I double the dose it improves my ability to pay attention and I am less distracted. Yes I have ADD but no longer take Adderall for it. Being 56 years old Magtein really improves my memory and restored it to like new by ten days of use. Shockingly It woke me up from a light sleep late evening as memories rushed in and I have been taking it ever since. I have been taking it 7 months now and over time it has slowly but surely improved my short term memory so that it also is nearly the same as before. I have seen slight improvements in working memory enough to be encouraged It may become an advancement from a historical standpoint. This is my second bottle by Teraputics. I was taking 2 bottles of NOW brand per month for my memory and concentration because it is the cheapest but when Amazon ran out Teraputics is the product I decided to try next. But I like this brand better as it seems more concentrated or I should probably say more bio-available so I decided to by it and pay the extra money over NOW brand. I just wish it were cheaper. I am hoping to ask them for a deal if I buy 20 bottles in advanced as it is a must have for me. With this second purchase they included a free bottle coupon and not a buy one get one free. Right now I am very happy to get the free bottle.

Daily Intake on Label Confusing
Label was not clear regarding milligrams per pill. Title label stated 2000mgs per serving (of 4 pills), but “supplement label” states 4 pills is 144 mgs per serving as a 34% of daily value. Very confusing. Not sure which metric to go by for daily intake.
