We have sold alot of kits without any major reliabilty issues. However one should expext increased maintanace and some issues once you get the kit on the car initially. The first few weeks are generally a big pain getting rid of all the leaks ect. Actually from most of the people that I have dealt with vacum/air leaks have been the source for most of the problems.
Once that was dealt with most cars run great.
Also on our stage 1 and 2 kits w/out th intercooler I have noticed they have had less issues because of just one charge pipe vs multiple pipes on the intercooler setup.
