running rich and backfiring

[drez]

hows it going you all ..... ive read dam near ever post that had to do with back firing or running rich but still doesnt clearly give me a awnser..... i got a 180sx with a sr20 det... now mod wise i got the basics

hks intake
blow off valve
greddy profec b
turbo timer
trust cat back exaust
down pipe
punched out cat
greddy emange
vac gauge

now some arent proformace but non the less..... im running stock turbo with stock fuel system.....

well the emange was doing good just a little rich nothing bad but since sunday i have been back fireing like crazy.... its not at low rpm's its when i get on the throttle prob around 5000 or so.... its not one or to shots it sounds like machine guns screaming..... a buddy of mine told me the emange might have not been tuned right (it was dyno tuned by the way) and he said to unplug it... i did and its still shooting flames.... like i said if i drive normal nothing happens its when i get on it and it gets up there..... im more worried about it hurting the engine.... i plan to check the plugs tonight when i get home along with the vac lines but i dont see how it can just start up so sudden..... any imput or links at all ould be great... thanks ahead of time people......



PS

We got time trial this weekend so i need her up and runing.... thanks
