will i be okay driving 10 miles on a 42# tune on my 60's on my way to get it tuned or should i do a parking lot swap early morning, pre-tune. I would really like to be able to do it at my house but if i can't i'll do it there. Also will it be fine to swap my pulley before or should i wait. Not as complex i know but if i can do it all at once that would be great.

Thanks for the help

 

it would be best to do it in the parking lot. the pulley should be fine to do at home though... just don't go full throttle on the way to the dyno shop

 

your ok to drive, just dont get on it. try to stay out of boost.

 

Thats kinda what i thought but it makes me a little paranoid

 

I had a stock chip in my 87 gn with a stock chip (36lb injectors) with 42.5lb injectors and it ran like crap. Fouled out my plugs and stalled pretty badly. I got the car like this so I don't know how long it was ran like that but the previous owner said he didn't even drive it since he bought it and put the chip in because he couldn't figure out why it ran like that. 009's (42.5) and stockers are the same color so he didn't know.
