the major problem with maf tunes and front mounts is the long pipework causeing lagging maf readings best thing you can do is fit the maf and temp sensor after the cooler piping just before it enters the engine
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem

you would want to do that anyways, would give a more accurate reading of the air going into the motor.

SPK:BAS:RUNSPKN[mac,rpm] is very interesting, either a sign of a poorly set up car that won't take timing or a scared tuner.

Hard to tell without more info on the car. Judging by the inj muls the car would want to have monster head work and a cam as well as a really efficient cooler?

Also a little confused by this one
