Something just doesnt seem right!( I think)

Ok so for those of u that dont know my mods are 224/228 581/588, 3400 circle D, LT's and ORY, and 4.10's with a trutrac.
on nitrous. jet sizes 61 and 38. Which should be a 140 shot
At the track its dead hookin off the line with the spray! ( I had way too much air in my tires last time which is y it wasnt hooking)
oh and a nelson mailorder tune..

Well 2 wks ago I had 90 shot and ran a 13.9 @ 99
last night I ran a 13.6 @ 99

2 wks ago//last nights slip read..

60' 2.08 /1.92
330 5.82 / 5.61
1/8 8.94@77 /8.7 @ 79
1000ft 11.6 /11.39
1/4 13.9@99 /13.66 @ 99


Is it just me these times just seem high for all the mods i have done?

you're a 4.8 ECSB right? sounds about right. what was the weather like? seems like you should've picked up some MPH though

i dont want you pissed... but i build this same truck for a guy but a 5.3 and little bigger cam...... 150 shot.. how tall a tire in back??... my guy runs 12.30s........

your tune may be dawgin the truck

the times dont seem weird, just the difference in times, or lack there of...

What's your rpm going through the traps?

Nobody will piss me off i want all oppinions and thoughts, which is y i posted this thread!
Ok yes it is an ecsb 4.8 and the weather was the same on both nights, and Casey thats y i asked cuz my #s just seem a lil off from some others ive seen, and Im on 26/10.5 and im goin through the traps at 5800rpms..
hopefully Im gonna find a tuner somewhat close to me and have them check it out and maybe make a few tweaks.
Also since the fuel jetting for the spray is rich could that be playing a part in it also?

Need more gear, IMO. What rpm do you shift at?

have fun having someone tweak the nelson tune, or even look at it.

if the jetting is too rich it could kill your times. especially in the upper RPMs which could be why the MPH isnt any different. do you have a wideband?

I believe nelson has it shifting at 6500. Im hoping its the jetting im gonna go back friday and see what it will do.. No i dont have a wideband and i know i need one
