My LCR is on a custom code stage 2 and seems to be running fine. However BHP is down to 219 not its usual 258 and the MAF is only sucking in 178 g/s. Torque is normal at 287 ft/lbs and so is the boost peaking at 22.6 psi. Im under the impression that the MAF should be reading around the 212 g/s? Can anyone help me with this. Iv checked all the pipes and cant see / hear any boost leaks either

im kinda having the same problem you see


ive got a revo stage 1
torque is around 260-270 but bhp is only around 238....

ive got a Liquid gauge which gives me a realtime reading of the MAF.

so was just wondering what i should be looking for.... under full throttle, idle, blah blah....

any high maf reading will be on throttle, think of your induction sucking air in, on idle minimal air, soon as you blip the pedal it sucks air in, the g/s is the air measurement.

maf should increase through the rev load and peak at 210g/s plus for lcr stage 1/2
