Sorry my post about lumpy idle should've read " after shell 91 " not 98. The reason ive been using shell is that we get 8c off a litre with extra coupons from our coles myer source card.
Ive used v power in most of my cars & haven't noticed any issues, although they have all been running aftermarket ecu's with custom tunes with that fuel in the tank.
Is there much difference in results between mafless & maf tunes with stock exhaust cars? From what i can see the KPM website prices a mafless tune around $300 more than the maftune & in the details mentions about recalibrating auto shift functions for the mafless tune.
Anyways i guess i can sort out that when i call them.
Is around $1-1.5k about normal for a custom tune on these beasts? All my other cars have been tuned @ $150ph & usually take around 3-4hrs max for full from scratch tune
