I just bought a Hypertech chip for my 87 305 TPI Transam. I know from reading the posts here that it's nickname is Hypercrap & all but I have neither the time or inclination to burn my own so my question is this, I have my timing advanced for better performance with the stock chip & the instructions for the hypercrap chip say to have timing set to stock is it OK to run this chip with the timing still advanced or should I reset to stock? My car is stock except for Flowmaster exhaust & K&N filter with a airfoil. I might have the car dynotuned with a custom chip later if I do any more mods so this might be temporary. By the way it is a Thermomaster chip so I know I will need a colder thermostat also.
I appreciate an info you guys have about this issue, this is the best forum anywhere for our cars!!!!!!

 

The Hypertech chip already advances the timing. You want your distributor set to stock 6 degrees so the chip wont overadvance the timing and make the engine knock or ping.

 

Thanks for the help. I will reset timing & try out the chip. I bought it used for $45.00 so if I pay to have the car dynotuned later I guess I'll just resell the chip on Ebay. Thanks again!!!!!
