Alittle dissapointed...

Well went to the strip last night.
First run was a 15.1@90 2.28 60' and an ecsb w/5.3 superchip,intake, and exaust was .002 slower than me with 2mph faster.
Second run, 14.9@91 2.24 60'and out ran a titan with boltons..
Third run, 14.7@92 with a 2.1 60'
All my RT's were below .095
On 26/10.5 et streets
My 60' times have improved by almost a full second but my ET's only dropped by about .5 and my IAT's never got above 105...
I personally think this truck has low 14's in it with my cam and stall matched, What do u guys think could be the problem?

It's a 4.8 with a huge cam and stall in an ECSB. You have everything but the cubes (or F/I) assuming you have LT's. Are you leaving at about 1500 RPM? Might try that. There's no way you should spin at all with a N/A 4.8 and ET Streets.

Yeah Nathan it dead hooks!!
Im just wondering if my mods are alittle too hard to get precise with a mail order tune..
And slim it's a 224/228 581/588 on a 112
Circle D 3600 verter
Luke dont worry!! There is already a kit in the garage, I just need to get injectors and a RPM switch

That doesnt sound right. On 20's with the factory 3.73s and all the mods in my sig, I ran a best of 14.17. My 60ft was a best of 2.2/2.3.

Tht doesnt sound right considering I pull a 2.3 60' with a 4.3 and 3.23's

^^ with a manual trans. There is not much difference in a chassis dyno of a 4.3 and a 4.8 on stock set-ups.

What do u guys think could be the problem?

Good work Chad. See, launching just off idle and letting the stall do the work dropped your ETs by .4! Now that you have baseline numbers with all your mods...time for a live tune so that you can get everything working together. Its a shame you are not closer so you can drive to Nelson and have him live tune it for ya...

Seriously, a live tune will make a night/day difference! I remember when I was running on my mail order tune and then went to Dale to have him live tune it...even after the first tune, it was crazy how much it opened up!

Ya I need tires all it does is spin with these 20s when I try and flash it, so I have to baby it lol. I'm thinking either drs or slicks on stock 16's.

Yeah I found a place about 3hrs away that does live tunes.." Fasterproms" I think eventually im gonna get nelson to send me an unlocked PCM and get them to finetune it..

Yeah Zach I know.. It will have to be 17's cuz 16's wont fit:argg:
I thought with the et streets that would be enough then I felt the weight diff between my 20's I took off the back and factory 17's there about twice as heavy...:(
