I am installing 30# injectors and I sent my Level 4 PROM back out to TPIS for reprogramming. What should I ask them to change. Look at the mods below to determine what should be done. Thanks.

For them to simply change the PROM to work with 30lb injectors it will take approximately 15 minutes including erase time. They will probably charge you at least $100. I say that it is worth about $10 + shipping. This is something that is so rediculously easy. You should do this yourself. And - TPIS will probably burn your chip for 30lb injectors when they really should burn it for 33lb injectors because the SVO injectors are rated at a different flow.

Thanks Tim. TPIS said that they would do it for free. I was planning on doing it myself but I'm waiting on a friend of mine that is getting the burning equipment. Can we copy the PROM that TPIS has made and burn it into the stock PROM, and then modify it? Can we save the info on the the stock PROM just in case we need to return to it? We are very new at this so we will be needing some help. Thanks again.

Jo,

Read the article linked at the top of this page. Understanding that article is the key. Yes, you can save the original BIN file and yes you can write to the existing chip.
