Re: Wot stutter

Personally I've never met anyone that had their car run worth a shit with 510cc and a 2g maf without atleast having a safc to fine tune.

^ this.

you can not run your car like this. take everything off and put it back to stock. even the MAF

go to this website click email the man and ask him to burn you a chip for your cars needs.

all your doing right now is hurting your car. the ecu doesnt know how to automatically change its brain to match to what you add.

also go here click and start at the beginning of the 1G DSM tech guide. read everything.

Re: Wot stutter

BigD on these forums can burn you a chip too. He burned mine and it's been great.

Re: Wot stutter

Why the hell are you running bpr8es plugs? Even guys making 500hp rarely run those. With your mods I wouldn't use anything but stock Bpr6es plugs. Yours are way too cold and my guess is that they fouled out also.
