MODESTO,
California
I have a 99 GSX with 55k miles on it and it runs like crap now ..
Ok where do I start..
I bought this GSX earlier this year here in CA and it had a bunch of illegal mods on the motor and a blown head gasket, So of course it would not pass Smog so I could get my 2012 tags.. I am a auto/equipment mechanic so I did the head gasket/ timing belt job and changed it back over to make it legal/ or some what legal to pass smog.. The main problem was the visual of my car when you open the hood, it had a Chrome Header with external waste gate, a GM MAF AND MAF TRANSLATER, ALSO HAD A GIANT SHINY 50 TRIM TURBO on it, chrome piping and large Blitz BOV.. it had large 680cc injectors.. and FMIC..
Ok so I got rid of the 50Trim turbo and installed a rebuilt HMI EVO 3 16g turbo, as it looks more stock than the Giant chrome 50 trim but now I have a J-Pipe .. anyway I put back the stock exhaust manifold and got rid of the chrome piping, installed the stock maf and stock injectors back in the car. I tapped a nipple from the J pipe to the new internal wastegate and ran a short vacuum hose.. The car looks alot more stock when you open the hood, but it has alot less power now..
I have been driving the car the way it is for about 4 months now and it gets from point A to Point B but you can tell it is not tuned..
The problems I am having are..
Runs Rich (you can smell the exhaust) I dont have a wideband or boost gauge
Dies out some times when the throttle is let off (possible boost leak)
Horrible on Gas MPG
Gets fuel cut around 6500 RPM
Takes a while to spool, almost like there is too much fuel or timing is retarded (dont have that instant power that I had before)..
This car has always run on stock boost, but it was tuned before at a shop to run optimal with the components it had as far as A/F.. Now I have mix matched components some stock some after market and its just not running right.. Its almost like I want to put back the GM MAF, MAF Translator, big injectors ect and see how it runs with that 16g..
I also have a new Wally 265 fuel pump that I have not installed yet.. I want this car to be a "sleeper" and look stock but be fast as hell.. I also need to decide how far I want to go with the mods because every 2 years I will have to put it back stock for a smog check.. Any where in Nor Cal /Central Valley where I could get this car tuned?
Also off the subject but... how are these AWD cars in the snow? I was thinking about taking it up to Lake Tahoe this weekend and its snowing... It never snows where I live ..
