ECU retune from Technosquare...there are some issues here. He has Beatriz's ECU to tune, but has not responded to her (his?) e-mail as to what the status is. Was supposed to be done end of March or beginning of April. Technosquare definitely has a deserved following, but are hold to get a hold of unless you roll over there (Cali.). They have results of at least 15 whp on stock cars for most Nissan models while staying in the safe range of running. With each additional performance item, that number increases. Check them out with a quick google search. Just an FYI, there site isn't that refined.
Someone already mention the Triple Dog GT Tuner due out this summer. It will eliminate the rev/speed limiter, but there is some question as to whether or not we can adjust the air/fuel ratio. That adjustment is what will free up the ponies from the air intake and everything else. Our cars run rich now. I haven't been able to determine myself as whether or not we can adjust it with this tuner.
