what crank pulley are you FI guys using?? Well when I went down to get my car tuned about 5 months ago my tuner told me to get a different pulley or use the stock one. Im currently using the ASP underdrive pulley, but I was told this can hurt the battery voltage which can creat spikes and hurt the motor! I no longer have Ac and the pulley I have has a ribbed area for that. The question is, should I get rid of it and get a ATI super dampner pulley for it? Or should I keep the ASP. I hope if I do decide to change it, I don’t loose any power. Things I figured it would help
Turning weight on the crank
Lighter pulley, possibly
No voltage spikes
Please feel free to chime in if you have had any of these thought, or have gone through the same thing thanks!

I upgraded from my stock pulley the the ATI Superdamper so I could run a custom 8 rib for my charger, but since your turbo that may be a totally different story in your case. But I think the ATI damper would be a good choice for you, I like the way it runs on my setup. See what other comments you get on here and go from there! Just my .02

By the book, you can't run 10s with anything other than an SFI approved damper (ATI). Many of us s/c guys also run it so we can use an ATI or other large crank pulley. As for U/D pulleys causing problems, yes they can. Been reported to cause under cooling, under charging, even harmoics that create false knock. All I got from mine was a 5* increase in water temps, so I sold it....

I ran the asp, but was having trouble with fuel pressure dropping. I then switched back to my stock pulley, which helped the fuel pressure.
I next bought a new, slightly more powerful, batter to replace my 6 year old one
Now my fuel pressure is pretty solid, maybe a 1 psi drop.
