having had the GQV for 2.8 years now, it was modded from the start...I think its time I start sharing the do's and don't's of engine tuning, from my own experience.
Software tuning - Only go to a reputable ECU tuner, not a file loader, if this person who tunes the ECU does not know that there are limiters and he can't remove it or don't know how...walk away.
Tuning boxes - it is absolutely vital to run a Spider/Novitec/Magneti within the limitations of the supporting mods(decat DP/intake/replacement airfilter/water meth/larger cooler). I'm currently using a friend's Novitec as I removed my remap some time ago as I was not happy with it anymore. The Novitec I have is broken, it needs an update as it gives errors the moment its connected. But Im running a replacement BMC drop in filter and a complete decat Supersprint exhaust. I've been on the WaterMethanol untuned for about an hour and the noise the pump makes did not excite me, but the immediate cooling benefits, even untuned, could be felt, we trashed the GQV and pulled over, put my hand on the intake pipe leading to the TB where the WMI nozzle is and it was cold as ice! its definately a worhtwhile modification to do if you find the replacement intercoolers for GQV's to be to expensive with little to no benefit reported by the owners.
BUT...imho I'd say for you guys in UK run 98 all the time...if you don't have 98 octane run an octane booster with the Novitec/Spider. remember these boxes are all the same, with only the hella expensive ones controlling fueling according to boost/timing...Novitec controlls timing/boost and TP only...which is BS.
So...if you are running that Spider with NO decat DP...get one soon, the heat you are experiencing is high EGT's that is rediculous as that car is probably boosting 1.4 or 1.5 with an overboost after 6000rpm of 0.1bar boost aswell...your EGT's are through the roof which will be bad for oil!
