Hey me78569. Got a favor to ask you. I have a data log of that surging I was talking about. It should be pretty early in the log. I drove around for about 20 min so there is allot there. The favor I ask is the 3 wot pulls I did. I just changed my turbo to a sxe369. Interested to see what each pull looked like. Let me know if you need help finding them. Should be obvious. They are right about in the middle of the whole log. One min while I attach iQuad-2019-04-17-07.39.521061791902337280395.csv

any reason it wouldnt happen when it locks up in 3rd? still low rpm

will do. i might take it out today. if not it may be a few days. supposed to rain all week

ill have to double check rpm. it was just a guess, but it only does it in OD when the converter locks. no other gears and not when its unlocked. i had this same setup without the quad and it never did it, as soon as i got the quad it started

it would be around 1400-1500 rpm. as soon as the tq conv locks up it will start to surge if im at low rpm 50-55 mph. im pretty sure ive seen in this thread that thats contributed to a certain setting on the quad. and it never did it before the quad either

i know its been talked about, but i cant remember where abouts, if at all ITT it was. what is the cause of surging at low rpm in OD? if im 50-55MPH in OD the trucks surges like crazy. above 55 its fine. under 50 the tq converter unlocks and is fine again

i would assume is not small turbos and small injectors

im looking without nitrous, anyone can spray an extra 200hp. but 800 would be impressive. i wonder what the set up is

damn i really wonder what the sovp record is. might give me something to shoot for lol

reason i ask is because ive looked on and off, just looked again now. and i cant find it

guessing monster pump? happen to know SO?

what is less than stock? what is the vp hp record?

isnt that still less than the quad at 30*?

highest timing im seeing there with the smarty on any setting is like 20* correct? looking at the quad logs it seems to be around that 30* area at wot

im just hoping i didnt cause any head or cylinder damage. the head gasket was just done last summer when i put the studs in. I need to get a drive pressure gauge and/or wastegate at 55psi. i know im out the efficiency range at 60-70psi do you have a graph or know what the timing is on say an edge or smarty? before the quad i had a smarty stacked with a tst powermax3 and the quad feels like i added a good amount of power. even my first time i drove it after got it installed (before i had the tuning down) i went WOT and my fiance said "that seemed faster"
