I already have gms1 ordered for my car but was wondering if anyone had used one of these on their card and the results. I can get on off a friend cheap. I plan to get a real tune but not till the exhaust, down,pipe and other bolt ons are done so I only have to tune it once.

 

if its cheap like under 150 get it . its fun until you get a real tune and i think it made more power than gms1 .

 

I ran it for awhile and it was decent ..... went 13.4@107 with it and it would have done better ( only 3 passes with it). There is a dyno somewhere with IIRC 285whp and 320wtq. I bought mine used for 150 and sold it for the same...... it was money well spent.

 

Good to know it was under $150 I ordered the gms1 for the new sensors since my tuner said it would be good down the road once all the bolt on are installed and I put a few more miles on since I still have the bumper to bumper for another 10k
