Some Quick Questions. JB3 1.4v

ok i just had a couple questions about the jb3 1.4v, if anyone can answer it will be greatly appreciated.

1. so ive reviewed the availble maps for 1.4 and just wondered what exactly lag fix is. and if it eliminates turbo lag why wouldnt people run this map over 1 or 2.

and

is map 5 safe on a stock car? what are your guys set up? for jb3 owners

Lagfix just gives you more low end power. Most run lagfix on but some prefer the non-lagfix maps. Try both and see which you like better.

Map5 should be used only with 93+ octane gas and a few mods. (atleast DCI) and preferably an exhaust mod like DPs.

Mike

P.S.

I would also recommend upgrading to the JB4!
