Here is what was on the car before the problem occured:
2g Gst
Evo3 16g, Greddy 24r fmic, Buschur Racing 3" catback with ebay downpipe, no cat, safc2 zeroed out, gm maft v2 zeroed out also, autozone filter with a hard 3" intake pipe, Ngk Bpr7es spark plugs and wires, and a afpr.
After installing my 660 Denso injectors and actually heading out to get it tuned at a shop, right as I drove out the drive way, my accelaration hesitated and stumbled. If I go slowly like really slow, the fastest I would be able to go is 30 mph, no more than that or else the car just bogs like crazy. I try to compensate for it with the translator and safc, no luck. The driveability of the car kind of reminds me of when my intercooler pipes would blow off, but would still be driveable since I had the gm maft. I was getting black smoke even before the injector upgrades.
My only guess would be a boost leak as I haven't done a boost leak test yet. Could a exhaust leak caused this no good acceleration? It seems like I was getting a exhaust leak where the downpipe meets my catback but I went back and tightened that up. The 2nd exhaust leak seems to be coming from either where the exhaust manifold bolts up to the engine or where it bolts down to the turbo as I see black smoke deposits around those area. I do already have a 255 fuel pump but I was going to have a shop install it for me incase you are wondering about my fuel. The bottom insulators of the injectors are new too. Pretty much the car just went to hell after the 660 injectors install. Sorry for the long description, I need this car running so I can drive it to the shop to get it tuned badly. 10-11 mpg sucks especially with Premium gas price.
