2000kms ago she reached the quarter mil...

Went for a health check and ran a dyno to see where it stood. Besides the Forge dump valve I installed, I had always thought the coupe was stock. What I found out was rather surprising and literally kept me up all night.

I'm pleased with the power, but she's running like she wants a cover feature on Forbes magazine.
Had an exchange of notes with her previous owner and discovered that she's:
a) chipped
b) running a Walbro fuel pump
c) 2.5" exhaust
d) balanced cams
While she was in Torino, I was told all the juicy bits had been taken out. Right down to the turbo timer. So I assumed I was getting a stock car. Seems some were left behind. Those I listed particularly.
Now, in regards to (a) I never suspected it was chipped since I did have a peek in the ECU casing and saw a Bosch sticker in there. I earlier assumed the boost spikes were resulting from a knackered EBV. The Walbro, if paired to a stock chip probably shouldn't be over-fueling (right?). So maybe it's still using a yellowtaxi special (with a Bosch sticker??). Will have to ask him when/if I see him or if he bumps into this thread. What else could make it run rich like that? Lambda sensor was changed when I bought the car. Richer is obviously better than leaner. But I'd prefer a stable A/F ratio in the long run. Thoughts?
Referring to (b), I'm running on a stock muffler. Checked. Yup. It's welded to something larger in diameter. So, okay la. That saves me a trip to the custom exhaust guy. If all goes well that muffler will be replaced with a Supersprint next week.
Another thing observed during the dyno run, it lost power (20hp to be exact) during it's third run and was misfiring. Everything else was relatively similar to the first run. Took out plugs and they were looking like this:

They weren't
that bad albeit very slight burns. Thomas said it might be losing power as the engine runs hot. So we switched to colder Iridium plugs and went for a few more runs. Same results as my posted dyno chart, but minus 20hp and minus the misfiring.
I'm not so much concerned about the power (238hp initial run vs 218hp consequent runs), but more on the A/F ratios and plugs (stock vs. Iridium), although it'd be good knowledge to know why I start off with a certain amount and then go downhill from there.
Somebody comfort me.
romeojay, thanks for entertaining my PMs.

I remember last time it was priced below rm1k. Kanasai.
