HI I HAVE A 2007 NBS EX/CAB 2500HD 6.0 WITH THE 6 SPEED AUTO .WHAT IVE DONE TO IT IS JBA SHORT TUBES(FOR WARRANTY) 3.5 IN MAGNAFLOW EXHAUST ,CUT OUT 9 MM JBA WIRES,AFE CAI & TUBE,EFI LIVE TUNE BY THUNDER RACING,NX 150 SHOT(WET) MY QUESTION IS WHAT WOULD YOU GUESS MY 1/4 MILE TIMES WOULD BE WITH THIS SETUP ALSO WILL A SUPERCHIPS THERM FOR A 2007 CLASSIC WORK IN MY TRUCK I BOUGHT THE WRONG ONE AN CANT RETURN THNX

 

i would say it would run low 13s for sure,

 

Is that tranny built up for it? If not youre gonna be losin a lot thru the slushbox.

 

I Guess Ill Find Out I Havnt Hit The Spray Yet Cause Im Waiting To Get Back Down South To Have A Nitrous Tune Added But I Still Need To Know If I Can Put A Thermostat From A Classic In This To Drop My Temp

 

You sure about that? I highly doubt those mods are going to knock 4 seconds off his time. Those mods in a 1500 truck would probably net him a high 13.

I bet you run a mid 14.

 

i dont know what you meen about 4 seconds i allreadt ran a 14.86 with just a tune on the engine and magnaflowe exhaust so i think low 13s ill be easy im lookin for low to mid 12s eventualy

 

Holy RU FN serious? In a 3/4 ton to boot?

I had no idea.

Mike

 

Yea that seems awfully screwy. That's damn fast for a 5.3L half ton. I know you have a 6.0 but still.....damn

 

yeah im serious random hero must have had some slow trucks bacause my last ruck was a reg cab 5.3 stepside and with just exhaust cai and a hypetech it ran 14.00

 

Its has 355 hp and 6speed auto stock tune and muffler its probably close to 375 to 385 there so much left on the table. I raced one with a muffler and beat him by just a truck and I ran 14.9 with my truck.
