I will be tuning it. On whipples tune, modified with Hp tuners. Not looking to be stupid with it. Will be datalogging all runs. I have a set of 1000cc injectors, and a set of 72lb injectors sitting here, but will not have time to throw them in by Friday. Was curious where the limit was with the fuel system supplied.

Very interested to see the results! Someone told me Atco was closed already though?

Open for private track rentals determined by weather. Surprised to see no predictions for time? It's hard to find information on where it should be time wise.

Assuming a good 60ft, I'd guess high 11's for the Stock Whipple stage 2 tune on a regular cab. Whipple's tune is safe, but weak sauce with no RPMs. If you get aggressive with it during your own custom tuning, then mid to low 11's would be possible on pump gas, and 10's on E85 or really really good race fuel. I've seen Whipple stage 2 regular cabs run 11.4's and 11.3's on pump gas with an aftermarket tune. The 18+ trucks really benefit from that 10 speed.

High 11's and low 12's. The stock Whipple tune shifts around 6500rpm, and that is leaving a lot of performance on the table.

Never ran the 2wd drive one stock. The 4wd (Identical, other than 4wd) one, went 13.53? @ 103 on the speed limiter.

I think my truck ran 12.6 bone stock with Whipple cal. I'm a pretty heavy crew cab.
Being single cab 2wd with slicks i'm guessing 11.6-11.8 on 93 pump gas and 3.75 pulley with Whipple cal.

Like BadCon said get some good transmission tuning and raise shiftpoints to 7500+ and high 10's should be achievable.

I put down 700rwhp on the 3.750 pulley with a tune from PDB. this netted me a best of 11.4@123 mph. I also have a supercrew cab. PBD reviewed the logs and fuel trims are perfect. I have been cleared to run a 3.5 pulley on 93 with booster or race gas. stay away from MS109 as it is oxygenated and will mess with the tune. run some good ole 93 and boostane or go right for the trusty blue. ( c16).. best of luck.....
