just wondering if i should get a performance chip or exhuast first


thanx....by the way it's a 1996 626

 

and also, if anyone knows any info about the jet chip system, that would be greeeaaaaat, because they kinda lost me, probably because i'm half asleep

 

Jet chips are shit on Mazda ECU's...the ECU goes into closed loop mode at full throttle, so it's working on preset values rather than taking signals from sensors,so the piggyback is useless...Spend the money on cat-back exhaust

 

KLZE swap ?

 

Fuck the chip. If you want to do anything like that pick up an S-AFC and put that thing on a dyno to tune some fuel out. But I'd start with intake/exhaust first.
