someone to trust for ecu mapping

[alex]

finished overhauling the f7r engine months ago and it goes like a dream. have not got round to remapping yet due to the canyon sized hole in my wallet and lack of renault specialists in essex. the engine has high comp pistons, cat 225's, pullys, gas flowed head, ptfe gaskets, full mongoose system with cat removed, etc.
only issue is power before 3500rpm. is this due to the cam profiles and pistons because the power comes in like a turbo. is this normal and what will i gain by mapping? anyone help please.............

Only person i would trust is Craig @ APD, but he maps cars on his mates rollers up in carlisle (until his own RR is setup)
