After a few weeks of waiting on various parts and 2 weeks of honeymoon, I was finally able to pick my truck up last night. Let me tell you it was worth the wait. With Mark's tuning and this new 72, the truck lights almost instantly, EGTs climb slower and peak lower, and the power is noticeably increased. I only have about 30 miles on the truck but couldn't be happier. I am only seeing 40psi of boost but I have ported heads and all my charge pipes and intercooler are larger than stock which could be the reason. I'm going to talk to mark and possibly send him a few logs but for a first shot at tuning the truck, it is one hell of a ride!!!! Now that I've seen the fuel these 60s will provide with proper tuning, I think I need to start looking into an HSP 483 twin kit.....
I`ve got a brand new s483 from Danville for sale if your interested....
