I recently put a new crate engine in my 1995 Chevy Tahoe, OBD1. Instead of going stock I put an ATK High Performance GM 350 Vortec Stage 1 crate engine and kept everything else stock. I have rebuilt the TBI, replaced all the sensors, added a EPROM + MEMCAL adapter to account for the additional horse power, but have an issue with the TBI receiving too much fuel.

Any suggestions appreciated. If you thing the ECM needs to be replaced, any ideas where to get a good one at a reasonable price?

Thanks

Pat
