I have an 07 GT/CS. Im currently running 12lbs boost on a 76mm Turbo, and have my methanol injection to inject at 4lbs boost with 50/50 mixture methanol/water. Is there certain ratio between lbs of boost and when methanol should inject? Or is it a personal preference? what is a good setting for it too inject?

The car seems to be sputtering in boost before 2nd. And seems to be taking a 2-3 second delay after shifting into 2nd.

 

Could be wrong...but part of the delay or lag just might be????? because of the size turbo (larger is not always better). When I went from a 67 to 76, noticed significant lag between the two. Car is used for racing and lag is eliminated with tbrake, 2 step etc etc.

 

4psi is a good starting point because at that low of boost there is no need for it.

did you have the car tuned for the methanol or did you just put the kit on? if the car is tuned for it, sounds like you have a sh*tty tuner, find some one else. if you just bolted the kit on, you need to go to a dyno tuner. that sputtering is caused by the motor being flooded

 

The car was tuned last summer at The Dyno Edge in Albuquerque NM, the motor was built by HP Performance customs in Roswell NM.. Took 6 hrs to tune the car. Used too be alot worse after it was done at the shop... It does feel as if its flooding itself sometimes.. If your not full throttle most the time it lags pretty bad.

I keep the boost at about 12 driving in town/street. And have kept the methanol setting to 4
