I'm still looking for that mythical 300/240-250 mark on a dynojet but it looks like it's getting a little winded up top.
On my car with a Borla EL header and headerback exhaust, it is showing:

75 mm: 8.5
70 mm: 11.5

Before the header I was seeing:

75 mm: 9.5

So I recon (but have not confirmed) figure 12 - 12.5 if you don't have a free flowing header/exhaust
