Upgrading chip

[Westriver87]

When my car was basically stock I put some of erics 60lb injectors and one of his 6.1 wideband chips in. I just got my car back together and have upgraded to a te44, precision slic, alky, shorty intake, etc. The question is: can I tune the fueling and timing for these mods or just go ahead and buy a new chip from eric? Thanks

You can adjust the settings yourself if you want. However, if the ECM loses power, it will revert back to the defaults. So, typically, its better to reprogram the chip.
