My car kept holding back after 4k rpm
 

Everytime I stepped on it after 4k rpm it was holding back, idk why. Could it be because of the warm whether? I have a white out frs, injen intake, srt header back, and it was tuned. I reflashed it last night and I didn't have this problem again? I was hoping, maybe the white out would reflect the heat.

my guess is bad quality gasoline. lower octane retards the cam timing.

Could be the intake, next time it happens get some logs and send them to your tuner.

Bad quality like how?

I always use premium 93 octane. I was thinking the same thing

hmmm depends what brand of gasoline. some use more additives and some not as much. or it could also be just a bad batch like with a lot of dirt and crap in it.

Readjust your butt dyno.

In warm temperatures, the ecu dials back the hp. It was documented in a recent YouTube video posted here. Showed something like 15hp drop after back to back dyno runs without letting it cool.

Theres a difference between warm temperatures and doing back to back dyno runs. Dyno runs you're not getting anywhere near the volume of air through the car that you would get on a highway. I seriously doubt that heat is the issue here, especially if the issue went away with a reflash.

You're kidding, right?

ignition timing not cam timing
@Frsexxxy you probably either had learned knock retard or large positive long term fuel trims... my guess is the fuel trims because if you had knock retard before the flash, with no other changes, you would have it again.

Turn off your A/c

I'm just taking his word for it.

Lol no,
I always get white cars because they reflect heat. My 240 was white, my integra was white, and my frs is white

I've always wondered if the excellent seal of the engine bay, hood and bottom, causes a heat build-up.

I don't know about anyone else, but my engine bay is much hotter than my previous cars, without hard or prolonged driving.

I really want the side panels to vent - anyone done mods to that effect?
