Dyno will be this Friday at RT tuning to confirm that my issue is solved. I'm seriously thinking about switching my Gemini for the TDX V2.

Here is a dyno I've done recently at Hill's garage after my floor mat fix. This dyno is comparing my dyno without LTs/Cams to now. I did the before in 2010.

I also included pics showing the difference in top end between the two.

There are no lowend losses, i've also included my last RT dyno to compare.

I want to go back to the original dyno that showed the losses since I did the before on RT's dyno for a fair comparison.

Remember this a DE with cams similar to SG's they used Nismo's. So a non-cammed DE may not see similar gains.

topend before LTs and Cams compare at 6700

Yes and a 6mt would have more due to less drivetrain loss. I have mild cams compared to you what you may get so you should gain more.

I originally ordered Kelfords, but the earthquake damaged their facility in NZ. So I had to change to JWT. Didn't want anything too lopey which I don't have with the S1's.

Impressive gains.. I want to do Cams on mine with HR buckets, just dont want Headers. Wonder what my gains would be.

Probably 15-20 depending on what cams you get. I'll ask RT to give me a dyno sheet comparing before cams and after.

I remember my before was 250hp after was 269hp on RT's dynojet.

Good to see you resolved your problem. Hopefully you see teh same on RT's dyno, but i'm sure you can already feel the difference just by driving since the loss was so huge. Told you that the Prius swap was a bad idea.

Btw, didn't you have the momentum headers when you installed your cams?

what's the difference in the two runs here?

nothing Vince really tried to tune out the lowend drop by adding fuel and timing just a before and after of what he did. Once my issue was resolved I was 12.1 in that rpm range at Hills Garage.

That dyno is with longtubes I dynoed 269 with the momentums and cams with less midrange than the longtubes.
