diablo tune: poor performance

[macedo6466]

I have a 2014 Challenger RT the only modification I have is the catback (Flowmaster).
I flash tune the ECM with trinity T-1000 I installed the "diablo tune". Took the vehicle for a ride and noticed a loss In performance. Confused with this tune??? I thought I would increase HP.
So instead...
I installed the 91 octane tune. I do get a good response but it feels just like regular stock.

Any suggestion?

Log knock retard. Hemis knock. The head design is awful. It causes tons of hot spots, which causes knock. Its like a half assed partial hemi, mostly pent roof with various globs of metal stuffed in random places. You gotta dial that out or you'll definitely lose power.

[macedo6466]

Thanks for the advice. I will start logging the vehicle using the trinity.

Base spark: 30
Spark advance: 12 (+- 2) @ idle.
With the "diablo install" and "91 octane install"
Took it for a drive.. Not good at all.
Im going to install the stock setting. I get better performance.

Log "ST KR" and "LT KR". Thats way more important than spark advance.

[macedo6466]

Monitored:

ST Knock 0.00

LT Knock 0.00

Took the vehicle for a ride and it maintained Knock at 0.00 through all RPM range.

At all throttle positions? Thats very weird. I've never seen that on any Hemi, not even a stock one.

[macedo6466]

Yes, ST knock and LT Knock stayed at 0.00 through all RPM ranges and throttle positions.
I will run it again and record it.

Installed the original tunes. Was getting frustrated and just getting on my nerves that a $500 dollar device decreased my horsepower not satisfied. The original tunes gives me a better throttle response.

I have never heard of that as well on a Hemi engine. My Hemi stock, knocks like crazy.

Mike brought it to my attention so I will be doing some test runs.
I currently installed the original OEM tunes. I'm planning on logging OEM, diablo tunes option and 91Octane option. Once I purchase the 2gig SD drive. I installed a 16 gig SD drive and would not read it.

You can do all that data logging without an SD card.

So I monitored my challenger rt with the original pcm parameters. Checked for knock and rpm. I got the same results (knock: 0.00) through the whole rpm range. Could it be that my trinity is not responding?

Go to hemifevertuning.com and Sean can get it sorted out. I was experiencing the same issues with my stock 2011 300C 5.7, Sean unleashed the "Beast Within" on my 300. I am now very happy running Sean's tune.
