Kline manifolds, 200 cell cats and exhaust, 99 octane pump fuel - Your 93 is equivalent to 97.4 over here so our 99 is 94.5 ish over there.
Not cobb, mapping was done by 9e here in the UK

Very nice-is that 476 whp from a actual dyno run or estimate via vbox? If it was a dyno, was it a Maha dyno? Awesome numbers-trying to compare as mine did 466whp via a dynojet. Have you ever done a 1/4 mile run with it? Can you share your trap speeds if so?

That is just estimated from VBox, stock run estimated it as 330 WHP I believe
With a12% loss that is 375 crank so kinda ballpark but I wouldn’t read too much in to 20 bhp either way to be honest.
I’ve never driven on a drag strip I’ afraid, if I ever do then I’ll be sure to head to Rennlist and post up the slip. All I have are the following figures from
vbox:
60-100 mph 3.8
60-130 mph 8.4
100-200 kph 7.3
And one 3.9 0-60 on dragy with wheel spin from when the car was completely standard.
Sorry to the OP for the hijack, not my intention!

I’m starting to collect a lot of stock turbo data via dragy before I start any modifications.
Managed an 11.8 @ 115 with my C4. MPH seems a little down from where it should be. Backed it up with an 11.9 @ 115.5 right afterwards. This was on an unprepped surface (highway), not drag strip.

Draggy looks to be worth the cheese
Nice 60
1.8 is my best 60 11.22 at 123.7
