Are you clutch or a4..wonder if it could be slipping clutch or slipping auto trans? Would think it should pull to 6500 or so.

its an auto and it is slipping a little but not that much, mainly right after it shifts and it doesn't shift on the dyno....

I think you have to delete your map sae pid in your scanner and insert 2bar map. You need to delete normal maf sae pid and map sae pid.

So does i sound like its breaking up at the higher rpms..??normal tr8 might foul out in normal driving. any machine gun or other misfiring noise..
I think tr7 will be lots or tr7ix .You can run the iridiums colder heat ranges without fouling. .028 to .030 should fire that boost level pretty easily if things are ok with your coils and wire and the plugs are not fouling out. Have you looked at any of the tr8s?
I was planning to go to tr8ix in my car next year if go to around 15psi or so max. Been running autolite 103 at .028 no problems and many run them to high boost like 15,18 ,they also don't foul out that easy.
Too cold might be your problem.

ya with the PID thing... my pcm is the shitty 98 so i have to do it a little different. but i am loggin all the way up to 210kpa... not sure what he's getting at with the 85kpa deal, im confused lol.

i mean yes i can hear a difference in the motor in the upper rpms but not
real bad... i can deffinetly feel a difference in the pull though.

i will be able to tell if its the plugs when i pull them tomorrow and install the 7's.

IDK, figured i would write everything out so it was easier to compare to the dyno graph...... instead of off the log file....

I got the second walbro set in today.... I still have to wire the hobbs pressure switch and relay.

My MSD plugs also showed up today and i went and bought some autolite 103's.....

I will try to get everything installed and see if fixes it tomorrow....

Master Power T70/.96AR, should be good for more than 530hp on a 5.3 I would think

I thought the MP t70 would make more than 500hp... and though it would push a reliably up to 16psi.

Hmm thought read they could do low 600s rwhp.And why can't you also run it higher boost like 18 to 20psi?

Be curious to see if the plugs and wires help the problem.
