SLY..
I have been following your past meth posts.. In effort to avoid an engine job as you found I'm hoping to ease into it slow.. Motor is a stock 130FI with PL turbo, headshim. PL recommends max 10psi @ 2000ft on Prem-pump. Plan to turn on the meth at 8psi and run 12psi @ 2000ft, and upto 16psi at 6000+. Will mix some AV to start, and monitor the injectors and filters. Sean
