Finally had a cam installed... A few questions... So I finally had my cam installed along with a 3200 stall and 3.73's. Had it tuned and everything. Now a few things are happening that aren't big deals, but I was just wondering if these things were normal...
Sometimes when I put it in park, the rpm's with fluctuate from about 850-900 until it finally settles on 875. SOMETIMES instead of that, it will go to 500 for a quick second, then go back up to 875.
When I try letting off the gas, it gradually goes up to about 42mph on it's own. The rpm's try going up when I go through a parking lot, causing me to hold on the breaks a bit to keep it under control.
If driving, and I put it in neutral, the rpm's will suddenly go up, unless I'm breaking pretty hard at a slow speed, in which case they will go way down to about 500, and the car seems like it wants to die. Grant it, it never DOES, but I don't it go past 500 ever, so idk if it actually will.

Your tune needs some work. I wouldn't doubt it if whomever tuned it only did WOT tuning and didn't do any drivability tuning. In order to get a cammed car to really run right you have to do both WOT and let the car sit over night, and do the cold start and drivability stuff the next day to really make it right. Also my tuner tuned mine with both speed density and MAF to add to the drivability factor.

Your drivability tune definately needs some work, some more work on the VE and MAF for sure.. Could be a number of things! But, whomever tuned it should fix it for u right?
