Just got AMS flashed

About the tune. I started conservative with timing and worked my way up. We made more power and torque with up to 3 deg less timing than the previous flash! A safer tune and more power, what else could you as for?
I krept up the timing to the point where the knock sensor would pick up engine noise and start pulling timing. The reason I spend 2-3 hours on the dyno with a car and do a ton of runs is that I need to make sure that my tune doesn't trip the knock sensor. I tune it so that the timing stays in the high octane timing map. I leave the low octane map alone because this lets the car pull timing when it senses detonation, this keeps things safe! I know there are other people out there that set the high octane and low octane timing maps the same or very close to each other. This is not safe at all, especially on pump gas!!!
Also the clutch would slightly slip for a second when the car hit full boost. The only affect this had was the dyno graph would get a bump right at full boost for 200-300rpm.
The power was a little low, maybe 10-15whp low. For those who think you'd get 350whp on our dyno on these mods, it will not happen on SAE correction. A FMIC and LICP will pick him up 10-15whp at this level.
For comparison i tuned an EVO IX (STOCK) and made 290-295whp (up from 260whp). On highway pulls the car would pull away from a WS6 trans-am with an exhaust. A WS6 traps 106-107mph, that means the evo would trap slightly higher. I've said this many times, but a car making 350whp on our dyno will hit 115-117mph. Ironically this is just about what a C5 Corvette ZO6 traps and they put down 350-360whp on our dyno(405 engine hp). Do you see where I'm going with this? You must equate dyno horsepower to real life results to really be able to compare one dyno to another.
Did you guys see the video David Ackerson posted with him at Road Atlanta? Notice he would pull on C5's vettes, a Mustang Cobra, & porsches on the straights? All that with only 310-315whp on our dyno
From what I see there are many inflated dyno #'s. I wish everyone would use the same dyno and would have the same corretion factors, same settings, and run the cars a the same temperature, humidity, and alttitude. This is not realistic so just know that take caution when comparing dyno #'s from one dyno to antoher.

hmmm im having problems scanning the picture on my bro's computer so ill have to do it later or take a picture of it. As far as how the car feels, it pulls great, and the guys at AMS are awesome i dont doubt any of Martin's tuning abilities he took his time and fine tuned my car, he did everything he could to try and squeeze out a little more hp and he did it safely, thats the most important thing to me i rather have the safety of the car then a few more hp. 
for AMS ill be back for more tuning in the future.

heres a picture of it couldnt scan it. Also i might switch back to stock plugs for time being and try some copper plugs. The car felt a little funny after putting in the iridium plugs, like the car would kinda bog before i punch it.

That's what I want to see on my car. Engine knock, below average octane pumped from a 93 octane pump (bad gas), overboost due to cold weather and ignition timing numbers staying high as if nothing was wrong. <boom>
Glad to see that some actually put themselves in their customer's shoes when tuning.
Nice job Martin. Its like poker, you play the best hand you can with the cards provided to you. Keep it up.
I'm a firm believer that the AMS dynojet reads lower than most of the other dynojet numbers we see on the board. Those dyno numbers should put you right in the mid to low 12's at around 108-109

You either have a major power hindering problem or your car is incredibly weak, or the tune sucks, but I think AMS is the best EVO Shop ever so I doubt it thats the last one.

I can say this, Martin DEFINATELY knows what he is doing. It is not the tune!

On AMS's dyno awhile back I hit 313hp and 304tq with a mail in dynoflash and a/f ratio about 10.5:1 from 2500rpm all the way to the end of the pull. The difference in my mods compared to yours...I had an AMS intercooler and LICP, test pipe, AMS intake, and something you have I didnt, the 02 housing and 10.5 hotside. Just to compare numbers. By the way, I'm mikes friend from Damar, we met while you were having the work done there. One thing you might want to check into, dont know how much it affects power but are the helix dp and HKS exhaust a full 3" all the way through? I saw a post awhile back from AL at dynoflash where he measured some exhausts and the HKS I believe was smaller in diameter. Also, im sure the high flow cat is restricting you somewhat.

I just had my car on Buschur's Dyno with almost the same mods, minus the cams and made 284hp/269tq. Now that is a mustang dyno, so a dynojet equivilant is about 346hp/328tq or maybe a little lower on AMS's dyno.

i dont know dyno's are funny sometimes, for now im going to check into boost/exhaust leaks. Also i took out my BR8EIX plugs and put in the stock ones for now till i get some copper ones. The car didn't feel right after sticking in the BR8EIX.
BigAeVo, I wasn't aware of how other cars have dyno'd at AMS with similar mods. It seems as if you're right on par. You have to remember that your HFC is probably costing you about 10whp, too. What really matters is how you compare to other cars on the same dyno and what your trap speeds are at the track. When I was dyno'ing 300/300 with the mods in my Warrtalon package, that is when I hit 12.26@110 on 93oct. If you trap 112-114 with what you have now, then you're in good shape. I would not be enthused with 108-109mph traps, though.
Also, you didn't mention that your baseline dyno was with another flash. You should have said that. This means that Martin gained 17whp peak, and as the graph shows, you gained even more than 17 in certain areas. I find it interesting how the 2 curves are almost identical (kinda strange) with a curious dip at 5500rpm, but since it's consistent, I guess that is being caused by something in the car itself. Likewise, you can see the clutch slip on the first dyno, but not the second. Interesting.
