how do I adjust air/fuel ratio for 3400 swap?

[bullet]

Hey guy, other than sending my Eprom/Chip out to get redone...what else can I do to add more fuel into the motor for running a bigger bore and/or more boost out of the 3.1 TGP motor?

also what injectors should I go with? LT1?

 

 

here's the deal, I've got a project my buddy is letting me do with him, it's a 1990 TGP with the 3.1L, and we're swapping the 3.1 out for the 3400 block/heads/etc.

how can we compensate for the larger bore? we are ofcourse keeping the turbo set-up in it, just doing the block swap.

all I need to know is how can I richen the air/fuel ration? are htere any A/F tuners availible for the OBD 1 cars?

 

Thanks!!

Youll have to have a chip burned for the 3400. If you can burn your own chips thats awesome, if not you need to give all the information you can to whoever will be burning your chip. Its not on-the-fly tuning like OBDII

Hmmmm, maybe that should be changed....OBD2, must do some quick research

Youll be able to tune much better with OBDII, although Im not saying it cant be done with OBDI
