How do you know that? Do you know what mods are done to the car? Have you seen the logs which indicate that this won't run fine on his car
?
To the OP as suggested above, post some logs of boost, AFR, knock etc. along with the mods for the car and the more experienced people can chime in as necessary.

8-9* degrees of timing at peak torque doesn't usually go over so well on most cars, but every car is different. That is a pretty aggressive timing map, especially if this is pump gas. As for the fuel map, we would need some logs of afr to judge that. I would log the car if I were you, you are probably getting slot of knock counts

My personal car has over 200 dyno pulls on the same dyno testing different tuning methods i.e. rich with lots of timing, leaner with less timing, high boost with low timing, low boost with lots of timing. The best numbers where found to be higher boost with a leaner AFR and low timing. AFter the car comes off the dyno I log the runs on the street to test the tune in real life.
His timing map looks like my timing map on MS109 not on pump gas. In fact I cant even run that much timing on MS109.
Running that much timing on an 8 is rediculous. I have seen many Evos professionally tuned. You cant run that much timing on pump gas it will knock like crazy. I guarantee the car is pulling timing and running pretty rich.

I can tell you what it looks like, but I have been learning recently that there are cars out there that for some reason can take more timing. I think its an electronics or cam grinding issue to be perfectly honest but I have seen an 03 and an 05 that both took 5-8* more timing than any other car I have ever tuned. Changed the cams in them from stock to aftermarket and then all the numbers went back to normal.
It is rich "appearing" but if lean spool is still on those numbers need a 1.0 added to them to look right. Also as asked what fuel is this run on?

Here is the map (remember 24-25psi on 92 and holding it to 6k like normal):

Going to a more normal map the car dropped 40whp on the dyno at 24-25psi. It was all resolved as soon as we put cams in it. Even the fuel map ended up looking really really strange in order to get the AFR right on stock injectors. Like I said I have seen it twice in 250+ cars so I am sure there are more of these out there...somewhere.
