engine can take 50 shot without doing anything,and if you use it correctly.
it can take an aditional 50 (making it 100)if you do it in 2 stages.
and make provision for it.as in a serious race situation.
you would already have CAI
,headers,exhaust all which help in ingestion and expelling of the additional exhaust material.
the other part would be hi octane fuel(not regular gas and a few octane boost!)real fuel.
c12.c16,cam 2 supreme,minimum 95 octane mixed 8 to 1 with ethanol(not methanol)AV regular or the L one is green the other is blue might differ stateside.
correct plugs 1 step colder ngk 7s for the gts 6 for gt and plugs could be indexed with Intake
cars ecu must have been reset way in advance a couple days of driving.if your ecu reset recently chances are you would screw something if you run the 50/50.
the fuel pill for the 2nd 50 shot could be (i say could and not should because thats how i did it,might not work for everybody)the next step higher pill for slightly more fuel to be introduced when the second stage comes in.
