I was wondering if anyone can give me feedback on there experience with vp c85. I recently tuned on it and my car put down really good numbers and I was very happy with drivability. I do drive the car to every event I go. ive noticed the last 3 times ive driven the car it seems to run really good for a decent amount of time then almost feels like the tune is lost. car breaks up, drivability is shit. Its not the tune because as stated the car drives fine for awhile, then it seems like its just gone. Now I will add I notice it more when its raining heavy or gonna rain. I do believe C85 is relatively new in race fuel. my tuner said it could be the moisture in the air but Im no tuner so was just wondering if anyone else had issues or input

 

i wonder if the offset tables for when the car gets hot are not right. air temp fuel offset is a biggie.

 

Ok does this have to do with tune or fuel because the tuner drove around with me after the car was breaking up bad and it ran like a champ for 2 days. while hot and everything then seems like it just started acting retarted again. and if it was a failing part such as pump injector or whatever he couldn't fix a failing part by logging it for 2 minutes of driving. im just really really lost and have no clue
