Running into an issue lately when ive been working on a tune with my integra Well be taking some pulls everything working fine, then ill hit a wall like i see alot of people post about, right around the 4-4500 rpm mark Couldn't figure it out that night took it home checked over all my fittings and fueling and everything. All looked good, tried a few pullls and had no luck, so i pulled the original tune file i had ( tune was set for 10lbs with same set up) and car would be fine and pull all the way through no issues. So we went back out and tried tuning again and adding more boost (manual boost controller) got it up to 18lbs at one point and thing where looking fine, my duty was maxed out, but still had pulled all the way through, went to do some more adjusting to better the afr and fueling and then hit the same wall at 4-4500 where it would almost seem like i was trying to use a rolling anti lag. Tried to adjust the table to fix it again and couldn't. Re uploaded my old file again and back to normal no issue, a pull or two later same issue. Reapeated this a few times thinking the uploads are just getting corrupt, and was headed back to the house and then we noticed on a pull or two that the duty just drops out at 4400 almost every time and we can't figure out if its the ecu or where to look. Any help is appreciated IM going to upload the og tune file, the new file 18lbs, and hopefully two datalogs showing the dips
