So i will be tuning my car hopefully this next week with Hondata s200b.

Heres the car setup.

95 GSR with 144000 miles

JRSC at 6 psi
440cc DSM injectors
Walbro 255lph fuel pump
AEM short ram
DC 4-2-1 header

and STOCK EXHAUST

In the future i would like to get the RS*R exmag, but funds are a little low right now.

Will i be able to put the aftermarket exhaust on after i tune in the future? or will i need to retune?


Thanks

 

you'll run leaner with the new exhaust. retune recommended.

 

thats what i was thinking.

What if i tuned with my friends EVO exhaust, then ran the car for a while on stock exhaust until i could buy my own.

How rich would i be running? and would it harm anything in the long run?

Thanks again

 

well it won't be THAT much but your point of tuning is to get as much power as reliable as possible right? so either wait it out, or using your friend's exhaust would probably be your best bet.
