Question
OK im deciding on GEttin a new Pulley for my car or got for the PFYC PCM, i was reading on the FFP.com site for the pulley and they say something about getting a 1 inch smaller belt i was just wondering if this is necessary and another thing about the PCM do you recoomend returning the stock PCM for the 100 bucks or would you keep it and be charged 100 bux more and which would you prefer on doing first the pulleys or the PCM and which will i gain more HP from ??

Re: Question
The PCM will give you more power than the pulleys. Return the old one and get your $100 back. You can always have the new one reprogrammed back to stock if necessary. The PCM will change many parameters in the engine itself such as fuel mixture timing and etc. Well worth the cost and not hard to install.
The pulley will require a smaller belt since the tensioner cannot take up enough slack with the new pulley to keep it tight.

Re: Question
one thing on the PCM from PFYC, they do need to be tuned usually.
Finding a PCM tuner, or going to the dealer is about the only choice. Ask Gir-_-, he just done his a few months ago, he'll be able to tell you the specifics he went through to get his up and running right.

BUMP! and notification, send me a PM jmoney if you wanna know my whole process of the DHP PCM, pretty basic installation and I dont regret it... and it 'does' run on just 87oct just not as great as 'power' as one might say but... I think that colder air coming in does the difference/damage to the pavement
