Here's the Dyno Report....

When the dyno tune as done, they put a fan in front of the radiator, and a fan in front of the intercooler.
I now get told afterwards that the ambient temperature isn't an issue.......when originally he told me it was.......he's now saying that the intercooler is too small.
But it's an aftermarket intercooler, not a factory one.

I haven't had it out with this guy cos he's actually an arse to deal with & I've squirted enough dollars his way already. Left a sour taste in mouth. Tried negotiation but he's non comprehendo. Sadly, there had originally been no other options to go to; he was recommended...

Cheers for your input folks; appreciate this platform to try to find my way thru all the bullshit I was fed ha.

That’s unfortunate you have had such a poor experience with a professional Tuner. Do you happen to have a graph of the AFR and possibly boost pressure to go along with power curves.?

[gary007]

he did say the boost pressure was on the chart he had given as you see
its not, thats all he gave me when i rang him he said 16psi from memory,

[Benckj]

More so than the max boost achieved its useful to see when it come on and at what rate. Having this information can point to possible issues with exhaust, wastegate and even drop off in performance from multiple runs. Same goes for AFR and IAT as they are good indicators on engine performance or lack there of. Having an aftermarket EMS allows this information to be gathered, displayed and routinely analysed.

You should have the capabilities to do quick road run and record real world data rather than sitting on an expensive dyno. This alone would allow you to see if you have an exceptionally hot engine or not during boost run.

Laptop and a USB cable plus PC-LINK software. Done!

For comparison This here was the dyno results of my 2 at a dyno with no tuning done at all. 192.5wkw and 328.7wtq. The car has an ATS racing CT21 Turbo, 3inch stainless intake, 2.5in intercooler pipes and aftermarket sidemount intercooler, along with a full 3inch decat exhaust system, completely stock fuel system, and ecu. During these runs the car was running about 17-18psi boost

[gary007]

the charts have given a better idea where mine
should be with what i have on my mr2 thanks everyone.

[Alsw20]

Go see the team at NZ EFI on Mobray Street and see if they can help.

I remember MR2SIK made 291rwhp (217rwkw) there on a built gen3 engine with a stock ct20b @ 1 bar boost on 95 octane fuel back in the day before Nelson even got 98.

thanks have now a contact in ashburton avr performance was recomended
hes in his 50s has a lot of experiance with race cars.
