question for you guys
 
My butt dyno is sensing some unexplainable differences in performance as of late mostly low to midrange responsiveness. Sometimes it feels snappy and sometimes it feels like its turning 2 ac units. I've yet to log it but my oft is showing no iam fluctuation. Air temperature isn't varying enough to cause it imo. My car is a my13 with a new motor and ecu installed in early 14. To me, it feels like cam timing. My mods are Crawford power blocks and oft 93 tune. Thx in advance for your input.

is your tune optimized for the power blocks?

You're just sensing day-to-day differences in air density, relative humidity, etc...

All engines behave the same way. Give yourself a high five for noticing.

You might like to put a relevant title to your post instead of "question for you guys".

The tune is ots and I didn't take the time to synopsize into one sentence. Lol

When I have the time I will tweak the tune. I have my heart set on a header and may remove the cpbs then.

Jeez, I hope you're right. No cel, idles fine. You probably are right.

Performance is also seriously affected by the nannies. If you're in the middle of a turn, even with the long press the computer won't let you punch it.

Driving in heavy rain is the worst because it severely interferes with driver input if it senses even the slightest bit of slip.

I'm a die-hard nanny hater but I'm also an old fart who's been comfortable with pushing the envelope for a looong time.

Have a look at you wot afr it should be no richer than 11.8

Have a look at your LTFT, the most common problem for NA guys is an intake or exhaust leak both will usually cause abnormally high LTFT like over 10%.

especially check your craford block install for leaks or dislodged hoses
