Do they actuallly work? I have couple friends that have them and they say that there's a difference. How about you guys do any of you have them?

 

Not on these cars.

 

^^^ this.

 

TS FSpec is the only one worthwhile. But they aren't made any longer, and finding them is a rarity.


IVT, stock VS TS F Spec:




AFR, no AFC tuning:



IGN Timing, F-Spec:


Speed on a dyno, no limiter, that's 7100 RPM in 3rd, which is about 138MPH, never taken it past that, no reason to, but, as is seen here, no soft limiter or any of that past 130. I'm sure it will go more once in 4th but nah, no reason to:



In the end, you're better off going with something that you can control vs a cookie cutter.

 

i need to bookmark this ASAP.... cause this comes in handy when i try to explain that TS advanced timing with the ECU, both F and L-spec

 

For real!!! I saved those pics!!! NMex where you get that stuff from? I've been asking people what the stock VQ35DE cam timing was through the rpms and no one could give me an answer!!

 

A True Rarity, you should just give me yours....
