Sr20 running really rich and bad
i have a redtop sr20det swapped into a s13
i did the swap not too long ago
and its running really bad
its running super rich (lots of black smoke and backfiring)
it also is hesitating and cutting if i try to get on it and around 3 grand when driving it

im pretty sure the MAF is good
so im trying to find out what else it could be

what mods do you have?
why would you mod a car and not have it tuned before you drive it?

How do you 100% know its not your MAF at fault, and/or boost leaks? Because even visually, you can't spot some boost leaks. Make a DIY boost leak tester, their cheap and they'll help you find any.

Also, the MAF's are pretty sensitive so how do you know that it works perfect?

TY.

make sure it's the right MAF, that it's working..and if you have a boost gauge, post your numbers.
