Put it up on the dyno to see what it would make not too happy with the numbers but I do have a th400 and 12bolt with a spool don't know how much that's affecting it .also My tune is a bit rich n/a was 11.7 gotta get it tuned setup at 28 degrees at wot
Second graph was with a 200 shot 8 degrees pulled i think it's dropping fuel pressure bad put in recomended jetting from my nitrous outlet plate and went crazy lean upped it 4 sizes and this is what it showed didn't have any bigger jets so left it alone didn't want to hurt anything
6.0 patriot 5.3 heads 231/239 cam ls6 intake and open tsp y pipe on these runs
It's got a racetronix 255 with Hotwire kit on it thought that was good for 600rwhp guess not
The car weighs 3350 and has been a best of 11.00@121 on motor and 9.98@135 on 200 shot with recomended jets and -8 of timing but never had awideband on it can't believe I didn't break anything with that 15 afr on the juice is a Granade
Any help or recommendations of things to look at?
Car has only ever been street tuned on motor
Car is fast man. That's a good combo right there. Who gives a **** what the dyno says
Thanks man 👍🏻 I gotta figure out what's going on with the fuel on the nitrous I mite. Bite the bullet and run a a1000 fuel setup but kinda tight on cash so it's gonna be a while
That dyno must read very low as I have a 3200 lb weight with 379 rwhp and 357 rwtrq and ran 11.62@116.33mph. So you're definitely making more power than me

Yea I think so too I know she has ***** can't grip on the street worth a crap on m/t dragradials the owner of the dyno told me to add timing to it on motor so I put it at 32 degrees with my timing tuner from the 28 I had and picked up 10rwhp it made 367 with 32 degrees but I put it back down to 28 sence my tuner says 32 is not safe it sucks my tuner couldn't make it

Without a doubt it's reading super low as a 121 mph in a 3300 lb vehicle means it's making goood power...wayy more than 357 haha or even 367. What stall and gears?

It's got a 3800 but seems way loose on my setup and 3.73 gears
I'm extremely impressed. Any idea what the timing was from 3800-5500 rpm as well as the afr? Does it have a maf and if so what size?
Stock 85 mm maf from a truck and afr was 11.7-11.8 the hole way threw which is on the Rich side should be closer to 12.5 but my tuner couldn't make it the the dyno also timing was 28 degrees

But it was the same afr at the track right? Also whar rpm did you shift at in 1-2 and 2-3? Thanks a bunch
And you had the same rich afr at the track correct?
I'm amazed you got away with 28 degrees even at the peak torque area..what fuel are you using?
Thanks
Do you run your tank FULL
some friends I know try to save weight by running less fuel but then when spraying the G forces elevate and can uncover the pickup causing lean out issues or nose dive scenarios
