Hi,
Im new to posting on the forums, although ive been reading them for quite some time :smiley:
I have a Golf GTI Mk5, 2006 with DSG.
I have been looking into remapping it, but im not entirely sure yet. Either way I have been comparing 2 different companies (R-Tech and Elite Remaps) and have noticed that the post remap figures differ. R-Tech say 240BHP and 266lbft and Elite remaps say 240BHP and 258lbft. My question is, are these figures going to be roughly what i will get or deffinatley what i will get? And why do the figures differ like that?
Regards,
Craig

Hey, welcome to joining in :)
Aftermarket measurement of engine output is not such an exact science. You could have your car done at either place, then take it somewhere else and get completely different figures. Think of them more as a guide and care instead about reputation/feedback/etc on the company.

Our remap data base is now out of date.. :embarrassed:
We are unsing a new TIV+ mapping technique with is allowing us to reduce exhaust gas temps and run a much better timing map setup allowing us to get more power for the same boost and fuel levels.

The reason for TIV
The anti-jerk function detects oscillations of the power train and damps them out by applying opposing-phase torque interventions. The torque intervention is converted into an ignition angle offset by the torque interface.
In order to damp the power train oscillation efficiently, the torque intervention should counteract engine speed oscillations. Thereby the same effect is achieved as if the attenuation coefficient of the drive shaft is increased.
You can have more power/ Performance but still have exact same peak bhp. Peak bhp is only a reading at 1rpm point to show where the max hp point is.
Performance tuning is about getting as much power from the whole power band. The more average bhp the quicker the car.
I would be happy having a car with 230bhp and 200bhp average over a car with 250bhp and 180bhp average.
2hp peak is nothing, it could be a cooler day, better fuel.
The TIV and TIV+ mapping is allowing us to unlock power from the whole of the torque curve its not aimed to get peak numbers. The TIV mapping also transforms the car on part throttle light load driving. At the moment we are the only company to offer this full TIV reduction mapping for ME9 - MED9 and ME7.5 ecus. It wont be long before everyone catches up again..lol

1.8T K04 with stage2 and high flow manifold. This graph shows the same map back to back, the smoother map has just the TIV reduction added, so its running the exact same boost, fuel and timing requests. More power and EGTs where 120deg lower.
This both runs have a low filter in the dyno settings so show whats going on during the run. Most rolling roads will have high filters and the lower run with interventions would look smooth bust still lower power. having a low filter allows us to see where the opposing-phase torque interventions happen. But when we allow the timing with no interventions the graph is smooth and a lot stronger

For a mk5 I'd say get to Rtech. That's one of my graphs niki has posted and the difference is day and night.
For a mk6 I'd say get to Carbon.

I had my mk5 with full turbo back exhaust mapped by r- tech a few months ago and the results were great. (259 bhp) - went back a couple of weeks for the updated map and the difference is staggering , just cannot believe how quick it is now !!!! If you have a mk5/6 gti you need to get it mapped and R Tech are the ONLY people I'd use - fantastic map, great guys and amazing value !

Take figures with a pinch of salt; its all about how the car drives on the road :smiley:
Every customer is different; some like the old skool kick up the backside and others prefer smooth, progressive power
End of the day, you as the customer has to be happy and confident in the tuning company you pick and be happy with the results you end up with :smiley:
Equally there are different ways of tuning a car and not all are safe :lipsrsealed: make sure you ask the tuner plenty of questions about how they map the car :wink:
I've done a few cars which had been remapped by someone else and its erm quite scary of what they have or rather haven't done :lipsrsealed:
