maybe this is a dumb question but what are they tuning with? I'm assuming you don't have a piggyback. Do they have software to directly interact with the ECU's timing and fuel map? If so, do you know if it can be licensed to end-users?
BTW, when I used to tune my WRX, my target was 11.5 down to as low as 11. 12.5 is way too lean for a 2.0L running 18psi.

I've never did a baseline before because I was "afraid" I might have a weaker C32. lol, but based on the gains experience by others with the pulley, y-splitter, and filter, those should add around 35-40 and the chip should gave around 20-25. that's my estimate if my car stock could put around 285-290 to the wheel.

I agree, I'm just trying to figure out how we can get our name out there quickly!
Maybe we'll offer a discount to anyone who is willing to post around and tell other people about us, and about Speed Innovation Software?

thanks everyone for the feedbacks.
I'll have to say the spikes are probably caused by the dyno guy's working out how to use the auto, but the numbers are definitely accurate especially throught the last 3-4 runs which sees 348-351rwhp consistantly.
as far as the torque curve I'm loving the flat torque curve usable for all it's power all the way to redline.
I'll start sending some PM to who requested.

If people think the numbers are high its because its a "dyna pack" dyno which means the wheels are taken off and the dyno bolts to each wheel hub so inherently it can be 5-10% higher becasue there are no losses at the wheel-roller interface (as there is no roller).

don't confuse consistancy with accuracy! Consistancy is unrelated to accuracy.

if it's 5-10% like you said it's pretty much saying the dyno graph showed by jerry on other dyno makes only 300rwhp which with his setup it's not possible dyna-pack has 5-10% difference like you said.

it's more like 5-10rwhp difference with the wheels not being present. however both AMG-jerry's car and mine are done on the dyna-pack, so it's still accurate as far as it goes.

I once said that a Dynapak was -3 - 5% from the dynojet, but I was mistaken and should have said +3 - 5%.
However, the Dynapak is more accurate for tuning as it eliminates the "wheel to roller issue". I will continue to use the Dynapak until I get the car where it needs to be and then do another Dynojet run for comparison.
Frank - Not sure if I posted this or not, but I lost another 10HP from the racing cats and custom piping. Renntech seems to think that I'm getting air from somewhere else in the system, that the "map they provided me wouldn't run that lean unless there was a leak". So, they are calling Germany to see if another flash would help and I'm supposed to check for leaks or put the stock exhaust back on to see if power goes back up.....I put the pipes and cats on a few days after the above dyno, so I know it's not a leak. Looks like the ECU is going back to Renntech for more tuning. Wish I lived in Florida....

agree with jerry.
could there be a leak between the welds when you put in the racing cats? hope Renntech will be able to solve the problem

Actually, Renntech thinks that I have a leak in the air intake system. This should be fun to troubleshoot. They assured me that they map they used on my ECU should be in the low 12's. They also said that as soon as I punch it, it should drop to 12 - 12.3 and only move a little. So, he came to the conclusion that too much air is getting into the system and that is why I'm running lean. Personally, I think that the map is off and it just needs to be tweaked.

I really don't think that is it. I wish I had another modded ECU to try....Hint Hint. Want to drive over for a Dyno run and let me use yours?? I'll pay you for your trouble....
