Well someone is super good at photochop. NOT!! lol haha --> owned!!!

But seriously , I Believe you could hit that whp w/ a stock t25 , but I don't believe that was 7-8 psi. Maybe you had a busted wastegate diaphram and you were unknowingly overboosting. EH... wth nice dynos anyway:bigthumb

It was consistent boost 7-8psi, not going over. You can call the shop and ask for Reggie to verify the boost. Before this dyno tune i took the car to Jerdevelopment and got it dyno'd on the dyno dynamic getting a max whp of 220whp but only recorded 216whp down. The afr for the first tune after 3600 rpm was reading really rich like low 11's to 10's at 7psi. (jerdevelopment doesnt know how to use an afc neo, saying easy mode is the same thing as Pro mode, which easy only have 8points fuel correction while pro mode is 16point fuel correction). So i took it to Reggie at osr and we did the 16point fuel correction and made 247whp. also the lower graph was really bad dude to detonation, so we gap spark to .033 and retarded timing a little more. safe boosting all day long.

what the hell am I doing wrong? I have a t3/t4 on 10 psi with a jimwolf tune and I can only tap into high 13's...
Isnt your motor built w/ lower compression? mines stock internals. i have that higher compression adavantage, but i heard it means more detonation since i'm only running a t25. But my bro raced his firends 13.5sec 1/4mile H22powered accord and beat him like 3 races. so i think we might be in the 13's. BTW you wanna trade 240's when i get my motor back from my topsecret build?

nope, stock compression. I hear Jimwolf tunes run pretty rich on boost like 11:1 so that might be it. I haven't checked my compression but it's a '97 with 130,000 miles and it runs strong so i dunno, my car still pulls like a mofo. I think I'll pass on the trade, I love my kouki

but damn dude, that's nuts that your ka-t was cranking out 247 whp on a t25 at 8psi. I am skeptical, make sure you disconnect the bottle next time lol
