why cant i boost in 1st gear?
hey everyone, as some may know ive been working on my turbo(install), but i have a prob with boost in 1st gear. when at idle my vac is around 20(vac) and when im in first the gauge go's to about zero(boost/vac) but as soon as i shift to 2nd i have boost. this is what i have(if it helps) dohc zc t-25 turbo a chipped ecu(te) dsm blue tops and a 2nd gen bov. the bad part is im still using a 4spd tranny and as of know i dont have an intercooler. so why cant i boost in 1st?? thanks for any help

Most likely has to do with your tuning. What ECU program did you use for engine management? I would ask the person who burnt your chip what they did to the settings for first gear. Its a good thing that you dont boost much in 1st anyways to avoid blowing your motor in that short gear span. First only gets you to like 35mph anyways.
