I'll let Barbz comment on that one, but that fluctuation usually is a clear sign of a failing EBV. Our cars are very similar, you have a fleamap and exhaust and I have a GTEC 1, no oil recirculation system for the intake & HDI boost controller. Everything else on our cars is standard. OK I can't edit my original post, so here are my graphs: Power & Torque Power & Boost Power & AFR

I took some photos on the day. First thing 996 GT3 RS Barbz's Mean Green Machine Nick's Tipo And a Pink Coupe thanks to the dodgy camera! When I left I was greeted by this beauty, my favourite car from the 80's

505bhp 382lbft @ 2.15bar. My heart's not bleeding. I'm over the moon. That is an awesome result fair play!! Out of interest what were your AFR readings like? Perhaps you could share your graphs? Are you still on the factory ecu?

All and well having great peak power figures but the journey to 500hp can be an interesting one. At least scan it so it shows the X axis too! Can we see your graphs in full with axis (all three graphs please), and anyone else who hasn't put them up yet? Your car looks to perform very similar to Speedygonzales, same turbo etc, although Mick is still on the standard manifold.

All and well having great peak power figures but the journey to 500hp can be an interesting one On tarmac, both coupe's have unrelenting power deliver in every gear. Biggenz's has 1 main advantage due to the size of turbocharger, he's able to stretch the rpm threshold further in each gear by 1300rpm. I make up the loss lower down for a more track focused setup. Horses for courses.. I know I've been going on about my results for the day, but it's not all good news. For a start, I'm down 60hp from Flea's dyno. How did that happen?? And before anyone says the hearbreaker under reads, there were a few standard cars that made near enough exactly what they quote in the handbook. Then if you look at Barbz's graphs, he made exactly the same power as I did, with a smaller turbo and with more torque. And he has 600rpm spool on me. The only advantage I have is I can rev higher.

Are you still on the factory ecu? It is awesome results really, as Biggenz spec is not so sophisticated. Still using the standard manifold and standard cams. There is also no water/methanol injection to help things, and worst of all it was mapped on 97 octane fuel as Pero get's this free on a company card! It could see another 30bhp+ if it had the benefit of all these other things. Oh and yes, still using the factory Bosch ECU

Can we list any others that have a graph in fleas dyno league table so we can compare??
I'm actually making a new Heartbreaker league table where people can put up their results to compare.

So whats the verdict on these graphs? Any issues? The car is pretty much standard apart from powerflow exhaust and FC performance remap. Yes the boost does show some significant fluctuations, a common problem with the standard EBV. Can you feel these fluctuations on the road? The dyno can often upset the calibrations for the first few runs due to the loading, but if you feel the fluctuations on the road (or see on a gauge), then time to get an upgraded EBV or use an external controller. Send me a PM if you need any more advice.

My mistake on the Aquamist, but you did skimp on the good 99 octane fuel!! Anyway, you like your lag monster, why is everyone so scared of lag you would say Speedygonzales also has the same GTX3076 0.82 turbo as Barbz (standard manifold though), and his car also spools up 600rpm earlier with more torque and less boost than your car. It is just the very nature of the turbo you have, designed for big boost and drag racing!

Was Speedy's run in third gear?

It's brain numbing sometimes debating data, graphs and dyno controversies. Lets switch over to a more positive and interesting observation. Here's a bhp per ton table of the top two Coupe's of the day. Biggenz 20v 2.0l 505hp = 382hp per tonBarbz 20v 2.1L 485hp = 373hp per tonCars on our heels. Noble M12 GTO - (321) TVR Tuscan Convertible - (337) Ferrari F430 - (342) Lamborghini Murciélago - (351) Corvette Z06 - (361) Westfield Sport 2000 - (370) And not forgetting the highest hp recorded on the day.. The mighty Gtr R35 Skyline 569hp = 327 per tonShows heels to: BMW M5 (E60) - (278) Ferrari 550 Maranello - (287) Mercedes-Benz SL65 AMG - (295) Porsche 911 GT3 RS - (997) (302) Porsche 959 - (315) TVR T350C - (318)

Oh and I could show you a hundred cars that make standard power on my dyno. In fact, we had a Mclaren M1B on last week which has a 6.2 Chevy V8 on carbs. The engine was freshly rebuilt, it made bang on 550bhp which is the standard power figure for when it was built back in the 60s! Another M1B followed which was bored out to 6.9 litres and a few more tricks made 640bhp. Surrey RR is the lowest reading dyno bar none, if you think that makes it more accurate then your call. For me I want solid repeatable results between cars and modifcations, that reflect how the car performs on the road, and correlates with all the same data. We're they run in 4th then?

I'm sure I overheard Charlie speaking to the GTR owner saying it wasn't quite running as smooth as it should - possibly mentioned 'plugs' and the owner said it needed a full service. So it could have made more!

Back on topic
Moral of the story here is no matter who maps the cars they never read identical on different rollers.
As long as your happy with the car and how it drives then it doesn't matter what the dyno said. After all peak power figures don't add inches to your Richard.
I had my car mapped at FCP and got 550ish. The next day on a different rollers it got 583bhp.
On maha rollers it got 498.
My current setup got 579 bhp which is around 94% VE with a 2.5 using the 3076. On dastek it made 612.
On heartbreaker it probably would be around 530-550 maybe. But I will always quote the 612.
For all those who maybe got irregular afr results then try testing it on the road as no matter how your dyno or the mapper tunes it,there will be changes due to load and environment the dynos simply can't simulate.
