so i have a built motor and shooting for 400-450 whp with s300. i was wondering if i should also get prologger just to be safe. are any of you guys using prolonger with your s300, how you guys like it?

 

Shameless plug, but I have one for sale and it's brand new. I was going to use it with my Neptune RTP, but I ended up changing everything.

I have used them before though and they work great. It's a nice item to have especially since you can control RPM activated outputs to trigger whatever you want.
