Okay guys here it is. Please read what I am going to say BEFORE looking at the graph.

I am going to put up the comparison runs between the first dyno and the new dyno.

A few things need to be considered when looking at this graph.

1) This is possibly the first 6mt Sedan tested wtih this mod.
2) This is also the first car with 93 octane gas.
3) The dyno operator doesn't look like he went right down to the floor right away on the new run due to the air/fuel meter and lower tq at the beginning compared to other runs. The ECU was acting a bit strange at that point. So take this into account as well.

Now I measured with a ruler the distances between each section and then checked the lines. The car did gain about 18-19 TQ and about 17-18 hp in the biggest area around 4k-4800 rpms. This is a large jump! It also gained a little before and after those areas as well.

This is the most important area to gain power. Mid range power is what usually wins races. It is what makes your car faster. We rarely go above 6200~ where I lost a little due to the mod. You are only up in that area for a very short time.

Now understanding everything I just typed. Here is the new dyno graph. This is a dyno by a independent person MYSELF. Not by the company. This is TRUE results.



Now if you want to see the new runs by themselves, here they are.

So there is a noteable loss in low end torque and a nice gain in mid range... hmm

I don't like the idea of losing torque in the low end, but the gains in the mid range should make driving fun (not including the beginning of first gear).

For everyday driving I really don't think the RevUp needs to lose any low end torque though...

Does that also mean we can expect lower gains with 91 octane gas that's available here in Cali?

Just seems that the overall HP/TQ numbers are lower on the sedan when compared to the coupe, even though they have the same engine

If you read what I said you wouldn't ask this!

The torque was lost due to the operator not getting on the throttle fully. On the other cars it does not show any loss of low end tq. You get a ton more TQ and HP right after that.

Tony and DaveO can explain this better than me.

Are you serious? While I'm skeptical that there was any significant difference between the coupe and sedan for 03/04, from what I understand the revups in the 05 are identical.

The dyno results on the first page just look so much better.

You can't compare absolute dyno figures amongst those cars, period, though you *can* compare the curves.

Each of those dynos were performed on different days, meaning different conditions. Those dynos were even performed by different *types* of dynos.

These dyno sheets are not here to show you what your car will achieve. They are shared to show what kind of difference the mod made to individual cars.

trey.. the 03 and 04 (280hp) motors all run pretty identical usually within 5hp of eachother. while the 05s we've been getting has all ran VERY consistant - BUT we have not dynoed that many.

The tests on the FIRST page were preformed on the same day within 3hours max of eachother on the same dyno and ECU reset everytime with ONE burn run (first run)

I did read your stipulations first. But you are speculating on the lack of full throttle, at least thats how I read it. If that is the case, the numbers don't look to be affected that much past the 2.2k mark in any event. I'm very hopeful that this mod is as great as it sounds, I was just making my own observations of the dynos. I don't mean to step on any toes...
