Just need a few people's opinions on my dyno results preferably people who have experience with rb's or own a Vl My setup consists of A8 (130psi comp test average) 3582r JPC exhaust manifold 3inch two mufflers and 100 cell cat JD plenum PWR cooler Wade 818 cam Siemens 650cc injectors Bosch 044 Ice coil and leads Just had it tuned and power seems down Tuner said restrictive exhaust . Made 231rwkw@5300rpm 823nm@4300 on 15 psi 98 pump . Now previously car had made 198rwkw with gk tech cooler kit injectors and computer and 15psi 3 inch cat back straight pipe different tuner . I know dynos are not the greatest indicator of true power and quarter mile times are but just after an educated opinion . To me just seems low I was expecting the 250rwkw mark .

Theres an entire thread on peoples results with that turbo... Is the car Auto or Manual??? Why was it only revved to 5300rpm??? Mine made 302rwkw with that turbo, through an Auto@18psi on 98 a few weeks ago...as you said, all dynos are different...what does it feel like on the road?

What ECU?

It was revd to 6000 peak power was at 5300 Manual Dyno pull in 4th Wolf 3d v4 Tuner was under the pump and had a lot of cars to finish before Christmas and I just wonder if he rushed it, made it safe but didn't really take it further as it wasn't taken up to 18 and bough back to 15 just set to 15 and tuned in that . Hence why I want people's opinions

My setup is similar and last time I had it tuned made 233kw around 900nm was turning tyres easy and no lag at all,But I was having a heap of dramas with mine last time X2head gaskets and bottom end ,In saying that we made the tune "safe" 3rd time around and took timing out it,It only made 193kw That power figure seems ok if it's safe, but going to a different tuner now he reckons the way the the old tuner did it was sorta wrong and he reckons next tune he will piss 250kw in with my new cam, so there's obviously a lot of variables between tuners that I've learnt the hard way
