that dyno is pretty hard to make out. Can we get one with an averaged run between the 2 so it's easier to compare? The only thing clear form this dyno is that there's more peak. I can't make out which line is which for the rest of the curve.

would this mod require new gaskets?? i am about to click the "checkout" button. :)

I reused the gaskets from my stock manifold and throttle bodies. The gaskets are rubber and mine were not crushed or deformed in any way. Also, I remember reading somewhere that new gaskets are unnecessary.

Let us know how it works out. I've been waiting for more data.

I am going to Z1 on the 19th. I will get a before and after dyno with the Z1 Upper plenum. I will keep yall up to date. :tiphat:

How much they charge you with the dyno tune?

Ive already tuned there before so im not sure. ill let you know as soon as I find out.

Thanks would like to know also if there is much significant improvement in performance worth the time and investment.

What I'm really looking for is an increase in torque.

Last time I tuned there. I was 312/258 with G3 intakes and Injen exhaust. Now I have test pipes and under-drive pulleys, will get tuned with these mods and then have Z1 install the plenum and re-tune again immediately.. I have a 25 row oil cooler on so I should get consistent pulls since this will all be on the same day. I too am looking mostly for torque gains.

Got the car re-tuned over the weekend. I did a before run which was 295/245. After the Z1 plenum I was at 305/254 this was within an hour of each other. It was a rainy damp day so that might be why I was at less power than my previous run a few months back. I will have the dyno sheet up as soon as I get it from John. I will be going back again very soon for another re-tune due to unforeseen circumstances.

In all I can say that I feel a lot more power in the mid range and all around. I will give a more detailed review as soon as I get the car tuned one more time.

how did the power and torque look between 2500 and 5500? i'm on the fence about this or the m370 and most of my driving is in that range, so i'm trying to find the best usable power, without losing power up top (compared to stock)

I felt a big difference. I am waiting to get the dyno so as soon as I get that you will see the difference. It has a lot more power throughout the mid range.

Wait so how does tthis work I would have to send in my stock intake manifold?

No. U don't have to but if u do u get some money back.

No further information on this as well as a dyno sheet? Ever go back for a retune?
