    ok im running the greddy e-manage and driving regular i have no problem, but when i step on it..it starts backfiring and slow down... now when i use around 1/2 throttle i can winned the gear all the way out without it backfiring.... i heard its the e-manage and that it cant handle anything above 10psi..also heard that its the map sensor and i need to get a GM 3-bar map sensor...is there any way to fix it and still use the stock map sensor..if not want is a GM 3-bar map sensor and where can i get it from??

    thanx alot!!!!

    you're probably out of fuel and detonating- not back firing.

    the honda obd1/2 maop sensors are 1.8 bar, and can only read abotu 10.65 psi at sea level.
    however, they will throw a code at about 2 psi. the emanage, and all the other units, can stop that code- but still, the map is limited to 10.65.

    gm 3-bar can be found at gm parts direct.com
    do a seach, theres part numbers and such in the refence area.

    what size injectors are you running?
    what size turbo?
    is the emanagement tuned?
