I have a 97 psd 5 speed with a ts 6 position chip with s&b intake. Well the truck its self idles fine and runs great but say I'm driving in third and about 1400rpm and get on it the truck just shutters like a miss and like 5psi of boost and I let off some and get back on it builds boost and takes off it will do this too if I'm driving and do about 75% throttle but worse when I floor it of course but I just can't figure out what it is I got good fuel pressure oil pressure everything checks out some school me lol
mine would not do it 100% of the time, but most of the time it did. If you tried to get on it, it would stutter and stumble from about 1500-2000, than it would come on like a race horse. Its a 5 minute job to hook up a different IDM and test it if you can find someone with a good IDM that you can borrow..
