I am about to update my '98 GLT with ipd's ECU and exhaust. I am excited about the added power to the car, but was curious whether it is necessary to change the octane of the gas I am using. Currently, I put in 87 octane. Someone mentioned to me that it might be a better idea to put in the 89 octane, just because the compression is going to change in the engine. However, I was under the impression that the NOC sensors would take care of the situation. Is it truly important to change gas, or not really?
Also, can anyone offer some feedbck about the most effective way to get the stock exhaust off of the car. Is it best to use a saber saw, or will that cause some serious damage? Better to use some rust de-oxidizer?
Thanks so much,
David
