yup, i did the stage 1 on a stock 35i and it was quite a noticeable difference, surpassed my expectations
since then i have added fmic + cp + intake etc and running stage 1+, felt a great difference in power/response after the ER fmic brought my IAT down significantly
no errors no issues along the way, and easy enough a newbie like me can do it, go for it!
