I bought a 94 gt a few months ago and want to know if the old timing bump mod works on these. I have been seeing some people say yes and some say no? Anyone know from experiance. And does anyone on here know someone that could do a tune on this car for me?

 

not sure what you mean by old timing bump mod but yes you can turn the timing up.take out the spout and turn the timing up to 12 or 14 just listen to make sure its not pinging.

as for a tune what all do you have done to the car? if it stock no need for a tune really

 

Its just bolt ons now but I would like to tune it after I do h/c/i.

 

worked on my 95.....fyi, watch out for the plugs on the electric fans I believe there is a tsb on them. I ran all day at Bradenton several years ago spraying 175 shot with h/c/i never an issue, on the drive home the fans quit intermittently and I popped a head gasket, didn't know why because every time I checked fans worked. replaced gasket and decked heads, happened again....three sets of head gaskets before I caught the culprit.....
also, ultimately put an A9L on it and solved a lot of driveability issues I had with no tune, good bit of compression, etc.
