G-Tech lists all the reasons why the readings from it will vary from a track. They are very accurate if set up properly. They aren't intended to directly compare to track times, only to give you an idea.

 

I too, have heard they are VERY accurate...maybe a tenth off in the 1/4.

 

whats a g-tech? never heard of it

 

I posted a while back about my experiences and results with the G-Tech. I basically got laughed at and was told there was no way my car was making the numbers I posted. That's really not relevant I suppose.

So is the G-Tech accurate? Heck if I know. I was told it was. All the research I did on it told me it was. It did get very close to my dyno numbers @ 11psi and the "street" tune I was running. But not ever having my car at a track, I had nothing to compare speed and ET's with.

What I DO know is, don't put 14psi boost and a "race" tune on a factory 2V block and internals. They tend to hand-grenade for some reason with that combination. Go figure.[sm=shootshoot.gif]
