Im curious what plugs you guys are running on your 50 trim and what gapping. Im running the 7ix plugs, I also never gapped them I just put them in the car out of the box. I just put some race gas in the car and the ignition started breaking up around 25psi. I was thinking to go with one step colder does it make any difference on pump gas?

 

You should be running BR8ES gapped to probably .024ish I would think. Maybe someone with more expirience can chime in.

 

NGK8s gapped to .022

 

should gap to 0.022 or 0.024 with HKS DLI II on the 50trim on higher boost.

 

I running bpr8es gapped to .021 w/ the 50trim. I have the AEM ems, anything above .021 and it started to break up at high rpm.

btw you already created a thread, asking about this a couples of mothes ago?

 

gapped to .019
