Hello eveyone, I'm new to the forums and hope to be a regular here. I have had my Sonic Blue 03 Lightning for about a year now, and love evey minute of it. I havent done much to it yet other than a 40 series flowmater and a free WOT boost pressure bypass mod found here. http://rpmoutlet.com/boost bypass.htm I'm looking at buying a package deal on RPM outlet.com (Optio E "E-kit" http://rpmoutlet.com/lightning.htm ) and it comes with either the Diablosport, Predator or the SCT Stratagy. Also the guy at the SCT dyno shop is trying to sell me the SCT Excaliber 2. So, the question is which tuner is better? If SCT is better, then what is the difference between the Stratagy and the Excalibur 2?
