Just me being me!
Totally agree!!
BTW - I like your mods - what I was planning to do - but HDDP provided the contact info for the LET pulley on another thread - after I call them with a few questions, I might go big next week. I also plan on a dyno tune - benefit of living in So CA.
I plan on hitting the dyno again once I receive my upgraded ECU. Not sure if you saw my dynotune post but my A/F was good after installing the pulleys. The ECU on these cars can adjust up to 20% is what I have been told.
