Ok. I just put my motor from my talon in a new to me gsx. Everything went fine but now I have a problem. I have what feels like a boost leak but thats not it. It seems Im running rich. Before in my talon a had a really hacked maf and now I have a maf with the lower honeycomb removed and screw backed out, basically stock. The maf, wastegate actuator, turbo outlet pipe and intercooler are the only things that were swapped out, they got damaged in the accident. When I try to start the car, it takes a few cranks to get it started, never did that before. It then idles fine but when I give it gas it bogs down. After its warm and I give it gas it revs fine without the bog. I took it for a drive and whenever I boost over a few pounds it bogs down like its getting too much fuel. Also I smell alot of fuel when Im sitting there. I have a 190lph fuel pump for my fuel 'mods'. I was thinking with the near stock maf and the 190 that its causing this problem. What do you guys think? Let me know if you need more info.
 
well instead of using hacked 1g maf get a 2g maf and u dont need to hack anyting.
The best way to check rich/lean is with computer diagnostic test.Do that and then u ll know for sure if u rich or lean and how bad it is.
But since it is turbo u need to make sure that u have no damn boost liks.
