Thread: MY 3.4" Pulley & Supporting Mods

A PCM tune cranks up the line pressure when WOT making it shift harder and a shift kit would make the tranny last LONGER IMO, due to the quicker shifting there is less stress on the clutches.

As for the Mexico guy...don't get a local to tune it...unless you've got someone that tunes 3800's...or they'll mess your sh1t up. Try to find someone selling a PCM on here...or if you know someone in Cali...have it shipped there from 3800 Performance. Or if someone on the boards would be nice enough to buy it for you if you paid them Do they not ship to Mexico?

They do ship to Mexico and my sister lives in Philadelphia too. I just didn't want to order one tune for my current set up and then another one for when I drop pulleys. The local tune would've been cheaper than ordering one I think.

If your dropping to a 3.4" then you can run the PCM on a stock pulley and it'll be fine...they are programmed for a 3.4" setup though. If you don't plan on modding past that there is no point to skimp there...just get the mail order PCM.



It says full exhaust in your sig...is that not headers?

Therefore...you liar...that isn't FULL EXHAUST

it's kind of a long story. I've known a guy here for like 10 years who's been building drag racing cars longer than that, so I really trust him. The other day he was building a VW Golf with an M90 taken out of a thunderbird SCed. He said he had a guy comming in to do the PCM tune for that car and that he was good he told me that he wouldn't charge that much, so I was thinking of having a talk with him first and see if he has any idea of what KR is to begin with, that would be a good lead, but atleast I know for sure that he has tunned cars with a M90 LoL.

If that's no good, then I think I'll take your advice and order the 3.4 setup PCM before dropping pulley size.

Cold air intake helps a lot, reset your pcu if you do it
