Vipec ECU (http://www.vi-pec.com/) has MatCorr(MAT,TPS) table.
I think it is better than airden corr or simple MAT table (w/out tps) and good in tuning.
Aslo i have made more precise scale for MAT corr: Corr = {((Value + 280)/4)-100}. So (0)=-30%, (255)=33.75% and step 0.25%
TPS axis is a small cheat, it has same scale as boost vs tps table
