Is there anyone has gone Stg2/2+ and wished they had not?

Your graph looks better Robin then the one running a hpfp :signLOL:

....Yep, it looks to my fairly untrained eye that my torque comes on higher earlier and is a smoother curve.
I last ran 253 bhp (IIRC) at JKM but with a misfire. I'm planning to organise another JKM dyno day soon-ish.
Janner_Sy:
RRs torque does come in lower down, but from 3000rpm its neigh on identical. RRs graph is also scaled slighly better making it appear flatter. ie the scale starts 400rpm later and finishes abit earlier. Plus this is RRs best graph, the others are all sub 260hp. You can only compare the curves if the scales are identical. If not you have to compare the actual figures at individual points of the rev band.
Stage 2 will be better than stage 1+. but its also would cost around £800 more to go for a stage 2 remap with TBE, intake as apose to stage 1 remap, HPFP and intake
RR you say your settings are turned down due to the HPFP being standard. well that what stage 2 is, every stage 2 car is the same, they will give as much as is possible on the std fuel pump. It would be stage 2+ if you were running higher fuel pressure.

....I think this would be best answered by Keith at JKM because what you're saying doesn't quite match JKM's reasons for reducing my settings.
Janner_Sy:
stage 2 goes as far as possible on the standard fuel pump. stage 2+ goes as the car was far as possible with the fuel pump.
You had stage 2 with no intake before. This meant you could run aggresive settings without fuel cut. You added the intake, this increased the rate at which the car builds boost thus will result in fuel cut with a stage 2 car on the stock pump, hence they turn the boost and fueling down to compensate. The stage 2 is designed to go as far as possible without fuel cut, which is exactly what you want with a remap.
Carl is now running stage 2 software on his vRS but with a HPFP and runs much more aggressive fueling because he doesnt have to worry about fuel cut, but its more like a stage 2+ remap i guess.
similar thing with the stage 1 map and a HPFP. @ stage 1 you can easily get fuel cut, but if you add the HPFP you can run more aggressive settings and make alot more power. But thats more of a stage 1+ remap then.
As you always say though, its all about what your after in a remap. An exhaust has its benefits as it will reduces the EGT's but its expensive. The HPFP is a weak point on the car, so is a good upgrade.
As said before, next time id be tempted to go with a stage 1+ setup instead of a 2+, purely in hindsight and what i want from a car. I like performance without the noise.

.... :happy2: That's the reasoning, Sy - Exactly as Keith @ JKM said - I didn't fully understand your previous post.
I like my performance with noiz! :happy2: - At least, when I'm using the throttle.
