can the neuspeed chip owners give an update as to what is going on with their chips and their cars. Is it still running well or any problems like the check engine light or so forth.<p>

No problems whatsoever with mine, I've never had a check engine light, and I'm very happy with my Neuspeed chip. Best $179 I ever spent!<p>FWIW, I always fill up with the highest octane gas I can get (around here that's 92 or 93).

No check engine light. Under full throttle the car emits more exhaust fumes than normal - seems like a normal thing for any chipped car. I often smell the same thing from Acuras and BMW's - especially M3's. My milage has IMPROVED! 23.6 to 23.8 after three tanks of gas! I still would like to see a Dyno graph though!<p>Tomasz

I have had mine for 4,000 miles and it has been great. When I first got it put in the check engine light popped on. Anthony, at Greedspeed, saw my posting and called me and told me to send it back to check it out. <p>I got it back and it has been flawless.<br>

2,500 miles and no problems. Initially had the check engine light come on. Sent back to Anthony at GreedSpeed. Returned with no more problems. Great service! Best $$$ spent on car. Only one regret - I waited too long!! Go for it!!
