Default Re: MAFT Gen 2 - Anyone?

I've got 16t turbos.. which are basically just a hair above the 15gs.. The lean limit I raised to 14%. I tried the TPS at around 1.75 and it was running ok, was actually accelerating very smoothly yesterday.. today, the car was sputtering alot, even just at Mid acceleration.. so I jumped it up to about 4.0 quickly while I was driving. Now Im hitting full boost kind of slowly actually.. the boost builds, just doesnt have as much acceleration punch as before.. gets to 18psi and holds ok.. just still seems laggy.. seems like anytime I run my mainscale at -20 or lower its real laggy, so I usually run between -18 and -19 and get pretty good results.. I have a pretty much brand new lower intake that Im hoping to assemble rails, fuel gauge and 550s on.. not sure if I want to go AFPR yet.. and I hope to do the hotwire kit for my walbro too.. but then I can watch my fuel pressure, and I think 550s are better suited for my turbos..

AFR is set to 11.5 across the board, hit around 12 AFR at WOT and full boost, sometimes goes a lil richer, but not too much usually.
