Alright I just got my turbo and new motor in about 2 weeks ago. It has been running fine with no problems. Starting like yesterday it bogs/hesitates between 3k and 4k rpm at WOT. And then at like 4.5k it flies. Any ideas why this might be happening? here is my setup

b18b1
Rev hard turbo kit
DSM 450s
street tuned with Neptune

any help would be appreciated. thanks

 

Having the same issue, changed the dizzy and it fixes the problem but only temporarily for like a few days. If I were you I would begin with the cap, rotor, spark plugs (gapped at like 28). If it persist move on to the ICM and then check the coil. Other things you could look are the MAP, and the TPS sensor. Hope this helps.

 

hmm ok. its a new dizzy and spark plugs but ill look into it thanks.
