Went to the track yesterday, I think my times were decent, but I'm just wondering if there is anything I can do better? Sorry dont have anyway to post the slips right now.... But here are my times.
The track I was at was MIR and from what I have been told is at or very close to sea level, and temps were down in the 60s all day with low humidity. This was my first time EVER to the track in any car and Im just wondering how I did? Is there anything I can do better? Or is this pretty much about as as good as its going to get? All of this was done on the stock turbo and clutch on 93 octane pump gas.

Yeah, MIR is at about 300' and is one of the best tracks you'll find. You picked a good time to go with the great weather, too.
The driving looks good. The 60's aren't bad, although you shifted worse on the good 60' than you did on the weaker 60', which is strange. Your 1.72 had a higher trap and was half a second better off the line, so that should have been a 12.4, but you must have botched either the 1-2, the 2-3, or both.
Anyway, you could do a little better on the launch, but this is better than 90% of people running those trap speeds. However, I don't know your mods, so I don't know if the traps are good or not. You mentioned stock turbo, stock clutch, and 93oct, but those are normal and expected - you should mention the ACTUAL mods. My last time at MIR, I had stg1 mods (TBE, BOV, MBC, FP, SAFC) and ran 12.52@108 on 93oct but 12.15@111 with 110oct and raised boost.
My mods are in my profile and were just updated as of when I posted the slips. But here they are agian if the helps at all.

Also, on my second run I think Iwas shifting the car alittle too high just before 8k and on the first run i actually bouced off the rev limiter coming out of thrid. I was trying for a 12.4 on the second run and acutally a little disapointed I couldnt do it. but oh well hopefully by the time I make it back to the track next spring Ill have GSC S1s and a EVO 9 turbo hopefully with those and a little better shifting I can bring my times down a bit.

Traps are so-so for the mods, but not terrible. I ran 12.26@110 with those mods minus the FMIC and with the same base Dynoflash in great weather up at Capitol.
That sounds pretty good for your first time. Make sure you are shifting around 7000 or 7200, like warr is stating. I shift at 7200 that way the trap speed is always the same.

7200 is quite high for altitude, too, on the stock turbo. You should be shifting around 6600rpm here in CO. I shift at 6300-6400, but I have a steep dropoff in power from 5300rpm, and yours isn't quite like that.
Yea Warr my horse keeps pulling so I use it to keep the trap speed where I need it. Tourqe is only needed to get you moving and the HP is to keep you moving. I know you know Warr but some people don't.

The stock turbo doesn't keep pulling up that high, and you can see it on your dynograph. Your car is no different than any other stock turbo'd Evo up here. 7200 is almost too high for SEA LEVEL, but WAY too high at this altitude. Your trap is low for your power level, and that is probably why. Your traps would be higher if you shifted lower. When I first moved here, I shifted my first several runs at 7k like at sea level and was trapping 106s. I then started shifting where my dynograph said I should shift, and I immediately went to 109+. We aren't running the same boost, so our power curves aren't quite the same, but the logic still applies.
But the stock RPM gauge sucks and mine is off by 300rpms at high. so that is why I shift there. I hear what you are saying. But now you know why I say to shift higher. Just test you evo RPM gauge. They are off just like the Speedo.

Where did you verify that your tach is off by 300 rpms? I've never heard of such a thing on an Evo. Even 6900rpm is too high, so that's still not the answer.
I have a tac from my race can and it is only off by 50 rmp from auto meter. I had them test it som many times. I ran 9.6 in that and shift a V-8 at 6200 on that tach. I drove the can 4 times down the track and I keep testing the motor to see what it liked for shift points. and she liked it at 7200 on the stock tach. that is how I pulled a 13.2. On a stock cluch. Not sure if that is normal for this car, but in Denver that is really good. for a street car, with little mods.
