i have aroudn 5k miles since i been twin turboed, today was raining very hard and when i started accelerating, my car would not accelerate any faster, the car would jerk and lag for a sec before it slowly accelerates. at first i thought it was just my tires losing traction, but it kept doing that... i have no idea what it is.. but the last time this happened was when i had a utec and supercharged, my buddy accidently kicked my utec and switched a map setting, so i was driving on a different map than the one thats tuned so it was very unsmooth and i couldnt accelerate properly.. but this time i am on osiris tune, and its acting funny.. im not sure whats causing it this time.. any one have similiar problems?? thanks

Do you have traction control disabled? If not, it could sense slip and pull throttle momentarily (traction light would flash on dash). If not, it could be tune related - specifically relating to the tip-in conditions.

Do you have an AFR readout? If so, what is your AFR during the 'lag'?

hey hal, i thought it was traction control kicking in so i turned off VDC and it still did that.. i do not have an AFR reading rite now... i think it is tune related also but what would make it change all of a sudden?? my tune was fine all along would it change all of a sudden like that?? im running osiris btw

You probably have water on your ECU and harness. Dry everything out and seal off the main harness boot behind the battery.

your sucking water in your intake and its getting your maf wet, pull it out dry it off let it sit over night and your problem will go away. Solution don't boost hard in the wet. and buy a set of these http://www.knfilters.com/search/wrap.aspx

i have had this happen a few times aswell, clears up as soon as the maf is dry.
