Attachment 228373

Hey all

I recently installed the Tomei EL headers, then had it custom tuned with Revzone in Melbourne, Aus, who are quite reputable with tuning 86s.

I definitely have noticed a decent power increase when I'm driving, and the car feels heaps better with acceleration as well compared to before the tune.

I've attached a screenshot of the graph

The graph only shows axle power in KW. I'm not quite used to reading that (and I'm still learning). For the stock run, 92KW at the wheels seems quite low as a number? I'm not sure how to convert that to engine KW which by the books is I believe 147KW. And given that after the tune of 110kW at the wheels feels so much better, how much would that be roughly in engine KW?

It was tuned with 98 RON, other parts that I have are Perrin 2.5 inch catback, K&N Filter, Mishimoto Silicon induction Hose

if i math correctly, 92/147 & 110/X = 176 kw, roughly 236 hp, but that seems kind of high for tune & headers

The claimed stock 147kw at the crank is probably optimistic and is distorting your maths. That said, you've got nearly 20% more power which is pretty impressive for exhaust and tune.

At 4250 rpm its nearly 50% more power. That will make it feel faster!

it looks good and wuite obviously they are values at the wheels and not at the crank
