Hey all, I have heard Pro-M went out of business and I want a Pro-M MAF, was wondering if this was true as my bro just ordered his Pro-M like a week ago..

Also my water pump went out, should I just get a replacment one or a high flow one from summit or something? I have no cooling issues, but just wondering about reliability.. ALSO would it be a good idea to go ahead and change the timing chain while im in there? I have 121,000 on my engine.. Thanks.

yes pro-m is done
no you dont need a high flow pump. a $35 auto zone pump will be fine.
yes, get a new timing chain. should make the car respond better to the throttle and it will be easier to tune

well if your timing is dead on everytime then theres no need to replace the timing chain, now if it walks around it needs to be replaced

Cool, I just replaced the timing chain, it was easy, and the old chain did have a little play in it, and the timing did jump around a little. So that's finished, and I also got a Bosch Water Pump rather than a rebuilt one..

Ok, that sux, I went and ordered a C&L 73MM MAF from my local speed shop. It came out to 140 bux, that's an awesome price!
