This is my graph(corrected)...... now youd think I could bring it up to 7500 rpm.... but no, only to 6800-7000rpm and thats at only 16.5psi

mods: 16g, removed lower honeycomb, backed out the silencer screw, aircan hacked and K&n, 70 gph Denso, 2.5" turboback

the car doesnt really hit fuel cut.... i dont think so anyways, because most the time it just feels like it starts bogging up at 6000 rpm and thats were I'll shift.... doesnt feel like hiting a brickwall (although in this recent cold it does sometimes)

I had a bad boost leak, but I fixed that

I dont have a logger yet, so I dont know what the maf signal looks like

q: does this sound like I just need a basic tune up (ie:plugs, wires??)

actually I went out tonight and did a couple of pulls.....

it bucks real bad right around 6000 rpm, but after that it will still go up to 7000rpm, but it kind of stumbles......

according to my airfuel curve on the dyno I think its because it leans out....

thoughts???

The reason its going lean is due to misfires. Try putting new plugs in (NGK BPR6ES) with a new set of wires too.

thoughts??? When your a/f goes down towards the bottom of the graph, that's rich.

no fuel management.... just stock

I replaced the wires, and the plugs are brandnew ngks..... that didnt make any difference

I might try a AFC to richen the topend, of course I'll probably just hit fuel cut..... o well
