Ok im going to say it again!
f**k these Ebay tunes, they are just slight tweaks of the ecu which will all give the car more power....
Honestly the person to see about retunes is CEF11E a big poster on this forums.... ive had 2 chips tuned from him so far, all with perfect AFR's and massive power (currently putting out just above 230rwkw ish with highflow, injectors, z32, and the rest)
He knows his RB20s, he can make a tune SPECIALLY for YOUR CAR and YOUR MODS, reliable, great guy to deal with, and it costs the same $50 (last time i checked)
So up to you, Random EBAY TUNE, with changes that anyone can make...
OR
CEF11E tune, trusted SAU member, tuned many RB20s, much more specific and better.....
i know where id be spending my money thats for sure!!!!!!!!!!!!
So go on, PM CEF11E, tell him HAYSEY sent you, tell him your mods, send him some money, and have a custom tune made up for YOUR CAR!
These Rip off merchants on ebay are really starting to bug me, just to make a quick buck they are risking engines!
