how does my graph look?

im sorta new when it comes to this so pls comment on my graph and tell me how's the curve and behavior. my car made 325whp/321trq. my mods are 3" TBE, hks rs intake, walboro, and mbc at 23psi. AFRs were around 11.5-10.5 when boost.

i know the graph is really small but try the best u can and comment pls and tell me how it is. people tell me #s dont mean nothing but my friend made 350whp with the same mods as me and when i told him i made 325whp he wanted to laugh, but it was on a different dyno. oh yea this was done on a dynojet. so overall does it look good or is something wrong with my car?

Really,numbers don't matter as I have personally seen (on video tape) a Friends car that has the same mods as you plus Cosworth intake and exhaust cams with same everything else and put down almost 360 whp and it will slightly pull away from his friends IX that put down just over 400WHP and a ton more torque(almost 100 more) running the same mods and on Meth and higher boost
So 360<400 whp but on a "ricer roll" the 360 slightly pulls away from the 400 as that is proof that #'s are not much to worry about.

You're breaking up a little up top ... maybe knock ... maybe misfires. I couldn't tell you. The numbers don't seem bad though. What dyno was your friend on and what were the air temps?

Maybe ... I'm not 100% sure that's what's happening in your case. But, if you are seeing 3+ counts of knock the ECU will pull timing, which can cause a rough curve like you have on your graph. I would think misfires could do that as well, but I've honestly not seen a graph where there was significant misfire issues.

Find a "track" and log 4th gear. Or, you could also log 3rd gear up a decent incline for similar load levels on the motor.
