Guys, guys... I got 400whp on the dyno!!!!!!

Yes I'm aware of that. No two machines/circumstances are the same. Relax. I was just throwing out my numbers for a point of reference.

I tuned my AT a few weeks ago and netted an avg of +10HP and +9tq(peak gains were higher across the powerband). The throttle is more responsive and my power delivery is very even, and I'm no longer fuel starved at low RPM. I even notice an increase in gas mileage, like I used to get around 410-420 with some spirited driving I now notice about 450.

There are a lot of deciding factors on how a tune will affect your car, type of mods being one of them.

Your car was dyno tuned, right? What were the before and after numbers?

If you find some bolt ons that'll give you 80 hp, let's incorporate, and we'll both retire within the year!!

After i put a new tune in my 7 AT with the cobb, the tranney and engine have to learn again. It takes about an hour of driving till it shifts and runs good. When you flash the ecu you loose all the stored driving habits. Just use the MM mode for shifting and it learns quick.

VVEL is a bitch aint it

I am going to be shocked when someone actually cracks VVEL. I think VVEL is a way to save Nissan money with warranty issues. My friend that works at a popular Chevy dealer in San Diego told me that a lot of Corvettes come in with engine problems and most of it is due to tuning however the LS platform is so easy to tune, it is also easy to convert back to the factory tune. He said for the most part, the ECU still shows that it was once tuned with very very minor percentages which give clues but more than enough get by with a brand new engine or a ton of money for labor to fix it. Hell, if I was running a business, I wouldn't want to be paying out my *** for people intentionally changing my product then claiming I need to fix it because they broke it. Don't get me wrong I would like to be able to get a decent tune out of the Z, but I don't see it happening anytime soon.
