I have the V2 set up, with the 3.125 pulley, 370cc injectors, and stock ecu. I am still waiting on my 4:1 disc to come in the mail so that I can tune my car. Right now it is running so rich I cannot pull enough fuel out with my safc-II to be able to read my air/fuel on the dyno....at 4K my air fuel drops below 10:1.

I noticed yesterday that under boost (my boost gauge is broken so I dont know what psi) but I was at about 4.5K in second gear my car would stutter. It kinda felt like I would tap the brakes then floor it....I am guessing this problem is related to running super rich for about 1.5K miles....I am thinking possibly I fouled the plugs or I am killing my cat and it is slowly melting together. Anyone had this problem or familiar with it?

 

i have the same exact problem...even though im turbod..i dont thiink that matters...

 

Since your running rich, that is one of the signs. Your flooding the car. To be honest with you, if you dont want to deal with all that fuel pressure crap and fuel etc...get an emanage and injector harness. You wont even need a fuel pressure gauge. The Emanage does everything for you. You will need that 4:1 FMU disc. My car use to that alot. After dropping t0 4:1 that bucking stopped.

 

cool....just talked to ups and it (4:1) came in today....I will change it tonight after work if it does not rain and I will report back, I will probably change the plugs for good measure as well.

 

I am still running rich, but the 4:1 got rid of the hesitation...guess it just needed to be leaned out some
