Doesn't the meth/water injection interfere or cause damage to the stock MAF sensors? If anything they will be cleaner
How much are the IAT's being reduced with meth injection before the MAF and before the intercooler? Which leads into the next question: how much are you able to increase timing from the lowered IAT's?
Have you measured the effect of meth injection on the EGT temps and by how much they can be lowered?
Another great idea from GTM and clean install. When will the kit be availble from GTM?
