should i retune
I was wondering if I should retune my car? When I tuned it I was running it straight downpipe. Now I put a three inch exhaust. When I tuned my car I made 300hp and 220tq on b18b. Noticed a power drop but don't how much.

the difference between open downpipe and 3" at that power level should be minimal do you have a wideband o2? if so have your afr's changed much?

Re: should i retune
if you have any other parts you would like to get put on, IE. intake manifold, injectors, maybe race gas? Then you should get those parts in and go back for a tune.

yea that rich, like said above aim for 14.5-15.5 at idle, 11.5-12.0 in boost for pump gas depending on your set-up and tunners guts

thanks for the graphs, whats done to the LS?
My del sol with an LS should put down similar but higher HP.
Im surprised running a 3" exhaust bumped up your torque that much.

wow, same here. I got the crane all motor stage 2 cams, crower springs and retainers and same injectors.
Took it to the dyno today, my dizzy was on its last legs, kept on breaking up.
I would love to see some videos on how it rips.
