im guna get it on a dyno to see what it's pulling to and will choose either 4.30 or 4.56 based on the results.

im guessing its the same thing that happen to me with the new cam. I got more top end but lost low end so im waiting for money to get gears

The wideband will be hooked up shortly,Stuart and I have busy schedules,but we will get to it very shortly.
It needs to be done with the new headers either way,so there is some left on the table.

bout time lol, this is how i figured out what i needed, with the new exhaust setup you pushed the powerband up in the rpm range, now you gotta bring it back down or at lease match up to it how far can you brake stall on slicks at the tree? yeah wheatley needs to retune it, you been knowing that so has he, like he mentioned busy schedules, get the dyno and then see where youre at, you got a daily screw the rest go 4:56


take my new cam its not much bigger in comparison to the one i am running on now but it is 5* bigger on the intake side and 3* bigger on the exhaust side. with a higher lift what this means since my stall flashes at 4500 it might just be perfect for the topend power i will gain but as for the low end yeah i'll loose some plus in the mid range, if anything i would be looking at another gear swap.. but thats part of the hobby you gotta match everything up when you make changes specially with a cam or intake and exhaust. it all works hand in hand!!

your setup was perfect where it was at, you wanted more and now you gotta get it but at the expense of paying more to get there basically stuart we are both running out of the daily driving trucks thingy we are teetertotting DD or race only trucks even though we drive them regulary lol

There's only like 150 rpm diff between the 4.30 and 4.56... If you run the 1/8th a lot I would go ahead and do the 4.56 cuz every little bit will help. The only thing I would worry about is with your tire size and a 4.56 gear where would it be in the 1/4 as far as what gear it would be in when you trap. You don't want it goin into 0D. But if you would still be holding 3rd I would go 4.56s all day long

totally missed your post. my last 7.72 was in -1800 da or some crazy crap like that. this one was in -50 to 100. even still, i should be doing better than 88mph.

Get it retuned like Charlie said there is probably a good amount left on the table. Go with 4.56's since your pretty much all top end power now. Go to the dyno and see what #'s your making and where your power band is. With all these changes its just going to take some time and practice to see where the sweet spot on the converter is, where your power band is at, ect... Git r Dun bro!

Or you can buy my truck and swap your power train into it!! Just kidding of course

damn I wish I could run in -1800DA!!!! I have never run in lower than 800DA. I do think these guys are right about the tune, but gears I dont agree with just yet. see whats left with the tune and go from there.

Im running 4.56 gears and a 4k stall in mine and love the gearing on it so far being i havent ran it wide open yet but its a good combo i think, your setup is somewhat close to mine and i shur like it but im a little worried about were my rpm is gonna be at when i trap with the spray. i had 4.10s in mine and swaped to 4.56 and were i noticed the most gain was in 3th gear.. much more top end.
