When I say is it worth it, I mean yes MRC maps are worth it, just is it worth it spending a grand on top of your current tune costs for the extra that MRC may give you on top of your current tune.
If you hadn't already had a stage map, then yes defo go for the MRC stage 2 tune, just is £1000 worth it for 100Nm (possibly peak, not overall, could depend on specific mods and actual bolt parts) and 20bhp, if there is much of a difference in bhp? Yes there is the power delivery which can also feel better.
I'm not trying to say, no point, just assess the 'actual' drive/performance difference over your current tune, and what you want from the feel of how the power is made and where in the revs etc is, that's where I'm discussing the 'worth it' or not.
If MRC were closer to me and prices were lower, I would have gone for the MRC tune.
We have compared an MRC graph with my More-BHP graph, MRC BHP is about the same and torque at bottom end is 15Nm more, +8Nm peak and top end is +5Nm, so pretty much similar, but the MRC car does have a slightly larger pulley, so this might be the extra!? Not the tune?
See if MRC will give you a stage 2 graph, if not, it's s case of if you want the ultimate numbers and splurge the cash on the extra digits on top of your map.
