I had Dom tweak my Prosystems 950, fuel curve was good going down the track, but my eyes would water in the staging lanes, air bleeds were unresponsive, idle was pig rich.

When I got the carb back it is was 19:1 on idle, but a 1/4 turn out on the bleeds and it's 14:1 to 15:1. Surprisingly it might be a tad rich at WOT...But the carb responds to every little change I make now, plus as an added bonus...I've learned more about carbs in the past month talking to Dom than I have in my 3 years of running one.

Last night at my first TnT with it I ran:
11.39
11.39
11.38
11.33 best 60 of the night, 1.55 best ever 1.54.
11.37
11.36
DA started out over 7400' ended up at 6600', the 11.33 happened because I was playing with my launch RPM, I went back to my normal 2500.
I'm ready to put some old school Mopars on the trailer at next Mopar Challenge series points race because race truck.

Very consistant. Sounds like you should be able to beat your old 60 ft. best real soon.

There's more there for sure w/a bit more tweaking but sounds deadly consistent...........Congrats............ It`s still down a solid.010 so when was the 11.27 best season wise and were the temps similar even though you said 6600+ ft..............

When I made that 11.27 pass I was several months into it for the year, I've made a total of nine laps so far, I'll get there, and track conditions were horrid...I'm not blaming the track personnel, we had a water down with antifreeze and the guy stayed in the groove all the way down the track. I was talking to guys in the staging lanes during the clean up, when the VHT cart appeared I said "Great, now someone will break a rear end"...The VERY NEXT pass a guy blew up his transmission.

I was so excited about going to a test and tune I backed the truck off the trailer without the ramps...No harm done except a couple Chevy guys helped jack the rear of the truck up to get the ramps under the rear tires...And yes, they teased me about being a MOPAR guy.

Sorry...

You`ll get it man..............

I remember the first test & tune os the season I went too. Was a 69 Charger, 440-4speed. High performance this and that, 4.30 rears, M&H racemaster slicks, blah blah.
Consistent mid 11 car. Then all the sudden I blew the tires off and went a 14 something at some killer mph. Anyways got back in line. Same thing. Hmmmm. Got
back in line, and for a third time, same damn thing. Went back to my buddies truck where I kept spare parts, jack stands, floor jack, and my M&H's still
sitting in the back of the truck.

This wasn't my first test and tune, just the second time out this year and the first I've raced for fun since last October...It was a kick, once I got the truck off the trailer....LOL

Action photo from last year.

Albuquerque? visited there last July testing a buddies stocker. Just a lil bit of DA!

Yep...Albuquerque. Capital of Green Chile Cheeseburgers and DA.

The truck is nearly a tenth off..........where is the tenth? Obviously it is not in 60ft if you nearly equaled your best. So is it slow from 60-330, 330-660, or out the back door. Look at the incrementals and figure out WHERE it is slow. If it is slow in the back half, is the mph down? Determine WHERE it is slow and your area to tune on will come from that

My best run Saturday was a 11.33, my best run ever was a 11.27 on a day when the track was prepped for the 8.5 and 10.5 crowd, track prep Saturday was for the street racing T&T crowd (as in none). I was launching at a lower RPM to keep from spinning, but, that 11.33 pass bugs me, I usually dial that in October, 11.38 is what I dial this time of year.

What was your mph? Did it pick up?

Never heard of anyone complaining because they went faster than expected. I blame that T humper guy for all of this.

Hey, I resemble that remark..........

Darn 2 circuit conversions, they just keep coming... ;-)

Albuquerque, my old home track, raced there from early 80s to 1994 when I moved to Phoenix.

Crazy huh Mark.............Damn Tuner, Shrinker, yourself and the rest screwin w/nature.............

I just looked, it did. I'm running the same mph a tenth off my best ET of 11.27.

?

They keep improving it, my first pass was in 2007, but Saturday night was cluster with all the oil downs, one right after another until all the junk broke and we could finally make some laps.
