Message was sitting at about 15psi. I'm getting VERY strange boost characteristics I think mainly because I'm having a very hard time setting the Profec. I have gain at 35% (is there a reason it won't go above 35 by the way?) Duty Cycle at 60% and set gain at 16. Usually the car pulls very hard and holds 15 to 16 psi with these settings (I just figured it out today a little better) but every now and then you'll get a pull to hold 17 psi and my absolute peak is 19.9.I'm trying to get it dialed in somewhere between 18-20 until I get an in depth tuning. Somedays I think there's a vaccum leak somedays I don't, I need to grab a tester and find out for sure. I check all vaccuum connections almost daily. I'm still working out a few other minor things (surging idle for one). I'm about ready to call it quits with the Greddy unit though grab a hallman and call it a day.The 113 wasn't really spin but more slip. I was working on how much to slip clutch and how much to just let out before I quit and thats how I got numbers to drop so fast while keeping 60ft slow. The 12.7 was slip a lot of first gear spinning the top and a small spin into 2nd. Haven't even had chance to get the car dynod yet, I've been waiting to get tuned. Which leads me to another question, I understand there's AEM but as far as stand alone or piggy back goes what should I get? Would an AFC with maybe an ITC suffice?
