Great Results... makes me even more excited about getting my C-Tune in the mail.. Once I have cash I plan to upgrade to the 80lb injectors Rogue sells. Sounds like these kits will become top sellers.

So +22 hp to go to the M-Tune vs. the A-Tune?
How did the curves look side by side, A vs M?
I love my A-Tune but am starting to think I may need to contact Josh and declare a credit card emergency here....

Re: Fuel Pressure Regulators.
Definitely check your fuel pressure! We've now had three different 3.0 bar fuel pressure regulators that were significantly off...
Re: A-Tune vs M-Tune.
We did do back-2-back testing between the A-Tune and M-Tune. Thirteen pulls in an hour. After testing the A-Tune, we swapped in the M-Tune hardware, and loaded up the software. No other changes; boost was kept the same, timing advance the same, target AFR the same, ect.
Here is the results between the two, and this is on a car that is turbo-flow limited; I would expect an even larger gain with people running upgraded turbos:

Also I think it should be noted that the sheet posted was not the best initial curve. I think it was just due to hitting the throttle later. If I recall the other m-tune runs showed a better response on tip in.
Maybe it would be wise to add those since they were pretty consistent. This just happenned to be the highest hp by a couple.

We need a another dyno day...
I started pulling the 951 apart last night to add the knock counter...
I probably need to go The Boost Creep (In Mead/Longmont) so I can compare befores and after on the same dyno...
But I would like to get some dynojet numbers.
And I am sad I can't opening day and Bandi tomorrow....best real world dyno there is....

Sounds like it would almost be better to get the adjustable FPR from lindsey, that way you know exactly what the fuel pressure is.. Instead of finding out wrong and have to get another regulator. Just my thoughts but I wear a helmet.
