Went back to the dyno this morning.
Results
This pull was at a max boost of 1.3 bar.
HP 490.7
TQ 454.9
Most other pulls produced about 480HP
Issues:
1. My VPC was working backwards?
If I richened the curve with the Gain knob, it would lean the curve. I tried this several times with the same results.
2. My igintion was giving me fits when I tried to turn the boost past 1.3 bar. The car would start missing bad.
I believe my plugs have about had it. I have been running Denso Iridiums at stock gap for 20k miles with no issue.
Can someone please advise.
1. Why my VPC works backwards?
2. What plugs and gap do you recommend.
I have one last question.
I tuned with a Fields SFC-R and had no problem fattening the AF curve up but when I am under light throttle my AF is so rich it chokes the car out and it stalls. Does anyone else have this problem with fuel computers. Do any allow you to adjust for throttle position or are all an on-off switch, meaning you either run the modded curve or you don't?
All in all I was fairly happy with my results today and I can tell this turbo has A LOT left in it. My HP curve just kept going up and when I tried to turn the boost up further I gained over 40HP and 40 TQ below 5000 RPM's but all those runs had to be aborted due to missing. If I could have stayed in it I believe I would have made well over 530HP.
I am going to change my plugs and go back to the dyno in a couple weeks.
Thanks
Josh
