| Post subject: | Plugs for 20psi |
hello everyone, i have a st205 with mines ecu and ive got a aem meth injestion kit installed on my gt4(lots of mods done)...my question is should i be runnin bkr7 or 8 plugs, i run between 19-22 psi and hav bkr7 plugs in the car right now. The car seems fine in the day when its warm boost is very smooth at 21psi, but at night i need to turn the boost down to around 17-18 when its cold out seems like the car starts missing. Also should i get a new fuel pump for running higher boost levels? thanks |
