I found some mis-gapped spark plugs some shop put in my car, then put new ngk plugs gapped to .30 in & she runs 2x better, but doesnt have "that" pull it had before. I check my AFR at WOT & it was about 12.0-12.5, is that ok??

Dont want something stupid to happen!!!!

 

how much boost? a little lean for my taste...i would run around 11.5-11.8

 

i agree. on a simple, lower power setup, it might be fine..

 

9.5-10psi off wg spring. I just dont wanna get on it & have something go wrong.

It runs absolutely great, not jumpy or running rough anymore!!!

It made 276whp on those plugs, i lost a little power but i bet on a good set of plugs & a better tune, maybe more power???

 

what ems are u running? I would add more fuel on ur boost columns...unless ur running lean overall, then u may need a retune or an overall fuel trim adjustment

 

AEM ems-1010

 

gap them closer, maybe .026 or .028. it only takes a second and is free to do

 

car is in my storage garage, ill try that 2morow, what is the benefit of that???

 

it helps keep the spark "together" and from blowing around with the flow of the air.

avoiding something called spark knock. i dont think your flowing enough air to make it necessary, but its a nice try. 12:1 isnt that lean that your car will feel noticeably different

 

yeah, the car ran ok before, but i pulled the plugs just for *****/giggles, #1cy=.32, #2=.32, #3=.28, & #4=.35

 

whoever gapped number 3 was trying to compensate for something.
and 12.0 is perfect for 10lbs
