12 PSI/Meth requires me to purchase the MAP sensor and harness and install, as well as the potential for causing problems down the due to 10PSI being the common thought of the limits of the engine. Also I feel at 12PSI any spike or creep in PSI could end very badly.

Do I tune to 10PSI/Meth stay safe and accept a spike or two past 10PSI not to exceed 12PSI

My tuner doesnt want to call me back, I guess spending over $1,000 in tuning doesnt warrant decent customer service?

 

Get the upgraded MAP sensor anyway!

 

gotta be honest, I am so tired of spending money on my car, if I stay at 10PSI Im not going to by the MAP

 

what happens if you spike at 10psi? Upgraded map is always a good idea.

 

Joey, read this thread on the stock MAP sensor

good question, I am not too knowledgeable, but what happens with the car/map past 10PSI?

I read it but still don't really understand. I wonder if thats why my car goes lean every now and then?

 

stock hg? - dont push past 10psi on stock hg with stock compression, you are already having a detination problem, stay at 10 psi.

 

hang on, I think I get it, the OEM MAP sensor doesnt see 12PSI, so if it spikes there the car will only be shooting enough fuel for 10PSI, therefor going lean?

 

I was only thinking of 12PSI with stock HG with Meth (50/50) mix

 

they really told you not to call back?
