That thing is surprisingly laggy (OP's) and no way it's making that on a single 255.

 

you guys have a lot of lag

Ive seen blacks spool faster and even 6266.....but I guess your tuner is using a tecnique to keep those rods happy but even so seems extreme.....32 psi at like 5500 then it has a dip.....guy has no control over 3port...

tscomptuned at least is making 600 whp doing this and the 3port graph looks nicer....I did a red over the weekend on stock block and mbc it made 520 whp at 30 psi on a single scroll about 17 degrees of timing up top and seeing full spool at 4200 rpm.....keep torque at 420

 

yes it is a bit laggy and i have been working on it since the tune. I believe I find the source of my problem, my dyno graph is with a boost leak at the throttle body seals. So very soon i will get retune and also changing my injector to FID 1300 so will see the new number. Boost should come a lot quicker than what on the graph with better number
