Default In regards to my last dyno run..

My freaking number 4cyl injector adapter was off!
Pluged it back in and idle smoothed out, and the engine revs a lot quicker. I figured something was up cause my car has been very slow to rev and has been idling like crap for the past week. I was thinking I got some bad gas.


Never threw a code and still had power. Just felt like something was wrong..

I forgot to plug #1 cylinder spark plug wire onto the plug when I did my header swap and drove it around for 2days before I noticed. LMAO. Weird cause I know the engine will set a code if a spark plug goes bad.
Never threw a code either. Threw a serious code when I collapsed my lifter!

So, are you saying that one injector wasn't firing? Were you tuned with the injector in this condition?

I was tuned with the injector firing.
It was not firing during the dyno run. I think the adapter got knocked lose when the dyno operator was hooking up his equipment. Car felt like *** on the dyno and on the way back home. I noticed it was off when I was playing with the Truck throttle body.

Are you going to re-baseline before your next mods? 275*8/7 = 314.

Man.. I really want too, but a dyno session costs about 90 dollars and I'm off to disneyland next week. Maybe when I get back?

^^me too! I'm not gonna lie, your numbers REALLY discouraged me from doing the swap since I've got the same setup except I have headers.

Maybe discuss with the shop and tell them the tech knocked the harness off?
