I currently run an edge with an A2. I have a HTT sledpuller 66 (set to 48-50psi), 90 HP dynomites, ARP headstuds, FASS 150, cp3 bag of goodies and tranny is built to the hilt. My question is I feel like I am running out of fuel when the turbo gets up to speed?? Dont get me wrong it pulls hard...REAL HARD but it gets kinda rough feeling and not as smooth as the lower end and there is practically no smoke at this point. I have heard that I need a smarty but wanted some real world advice maybe from someone who has made this same switch and with a similar setup as mine. Which is better? Not on price either...I just want the best. Is there a stack I can put with the Edge or should I sell it all together and look at one of the others? Any help would be great!!!
