i just got the basic kit, no custom map as i didnt think it was worth doing untill iv decided what i want to do with the engine. The car deffently feels better and stronger.
I did the performance analysis but the conditions wernt ideal, wet, dark, not a flat smooth road. We really only did it for fun on thursday night.
Im not fussed about gain's (as in BHP), i doubt ill ever take my car along to a rolling road day, unless its free!! But the car feels good, it accelerates strongly through the rev range, i am hoping ill see a benefit on trackdays with the increased rev limit, I think it needs several starts to learn driving style ... I mapped it again on saturday morning, so it may change up to 10 or so starts while it "learns", ill probably load the .cal file again when i fit my matched inlets and if i fit a decat/sports cat so the ECU can "learn" again with the new bits.
When im happy that im not going to change the engine for a while ill ask henk about a custom map.
at the moment im pleased and would recommend it over going and paying a tuning company £300 +
and you get to do tests and read and erase fault codes as i have the emissions light constantly on ill be ordering a new manifold sensor from renault tomorrow.
