LOL, I thought I was being fair Robin.
I agree that dyno results are lotteries, but there are quite a few who have changed parts/upgraded/done nothing at all, that have ended up with lower results from last time they were at JKM. Like you have always said, you go to JKM so you can directly compare your results and yet you aren't able to compare the current results to last time as you are down on power, but haven't got anything wrong!

....Firstly, my comment to you about being fair was in response to what you posted about '4WD' Haldex and Nitrous. You are forgetting what you had been previously informed about JKM's policy regarding both '4WD' Haldex and Nitrous. If you recall, I specifically asked Jim at JKM about these policies and reported back to you directly what he had said.
In my case, I'm down on power because, as my plots showed, my AFR and boost was erratic.

I'm not forgetting Robin, I was making light of it as it is no biggie :happy2: I understand perfectly what JKM's policies are and I appreciate them, but don't have to agree with them.
AFR and boost being irratic may have been your issue (although I think you had a 20bhp loss didn't you?) but others had similar losses and even went to higher states of tune, knew their cars felt faster, yet had lower dyno readings.
I'm just asking the questions and don't expect anyone to be able to pinpoint them, just highlighting them as I see them. :smiley:

IMO Robin, regular dyno days are good as they have shown up a potential problem... But would that problem be their if the RR was set up and loading the car right!? The ecu work on how they are being loaded... If you have not noticed a change out on the road, then what's to say there is a problem...
I'm not bitching, just concerned that I have spent a lot of money to get somewhere, and I'm apparently not there, or am I, and if I'm not, why am I not... I'm an engineer, if something's doesn't work, I wanna know why and how I can make it... But when it involves spending more money, of which the parts I have added should be giving me the results I want and are not then I have to question how they are being measured... I need to know what's causing this, as other have had better results with similar specs...
I'm even attending another rR day this Saturday to help me gauge this...
Would like to get to the bottom it... To only gain 9.3bhp over stage 2 is a bit of a let down, but there's many factors behind it I'm sure...
RedRobin:
.
I'm like you, Dom, in that if something is appearing to be not working as it should, then I want to know why so that steps can be taken to solve it. :happy2:
Consequently, in my particular case, because JKM know my car so well and have literally years of logs, I shall be asking Jim to do some logging when she is is there for her next service.
Meanwhile, she is feeling just as responsive as ever to drive. On JKM's rollers she has always fluctuated between about 250 and 270 bhp and always with smooth curves.

Why do JKM use TN:3.356
SRR use TN:3.541
??
