What's the min octane rating to use the ASP pulleys? Here in Vegas, the highest pump gas available is 91. If 93+ is needed, I'd have to mix with expensive 100 all the time.

 

I would think if it was running real lean the ECU would pull timing or something, but it still could be running lean enough to stress the motor over a longer period of time. Most power adders reduce engine longevity anyway, but just get it checked to be safe.

 

This would be my concern as well.

There are a couple of ways of getting a/f... you can add a bung to the exhaust system before the cats... something like the AEM Uego or a NGK A/F gauge... all they need is a power supply.

or

Or you can take it to a dyno shop, and they have a sniffer that goes into the tail pipe to get readings... but that's after the cats, so the numbers may not be all that accurate.

 

Awesome dude! Thanks!

 

Wonder what your 0-60 time is if you are running a 12.3 in the 1/4. Anyone know how to calculate that?

 

between 3.9 - 4.1 0-60 for 12.3 1/4 mile.

 

It seems like 0-60 is instant now...but this site puts me at 3.47 seconds.

My stock time put me at 4.56 so it seems fairly accurate.
