    Good to know.

    If the only value changed was the throttle scaler you are reinforcing my point. If he didn't have to touch the MAF and VE tables that reinforces the notion that it did not provide any additional airflow. Also, I saw that this was on a Dynapack...anyone can get those things to read just about anything they want. Hell, I have a Dynapack sheet that says a stock LS6 with a 112 Maggie @ 7 PSI and 1 7/8" headers made 487whp...that didn't happen either in case you're wondering.

    The mods I will be adding are below, anything else I should add or missing?
    Magnusson MP112
    LS9 Cam
    Comp Cams Trunion Upgrade
    Texas Speed Dual Valve Springs
    Cloyes/C5R timing chain
    LS2 Throttle Body/Harness
    You're dumping a lot of coin for absolutely no reason. The COMP trunion upgrade is no longer recommended b/c they're crap and have recently been puking the bearings more so than the OE units...COMP Cam's materials and QC are so bad that just about everyone is dumping them for Cam Motion. I believe Geoff at EPS just made the jump due to poor quality as well. There is an entire thread about not doing the COMP trunion upgrade over on LS1 Tech...I'll try to dig it up.

    Brian Tooley racing has the best set of LS springs available and the entire kit is $219...for everything. Really good dude to deal with also.

    The Cloyes chain is overkill, stick with the LS2 and save a few bucks. You'll have to get an LS2 front cover and a Trailblazer SS LS2 cam gear to make the LS9 cam work since the cam sensor has been moved to the front cover on GEN IV and later engines. A new cover comes with the sensor and you have to extend the cam sensor harness and swap the outer wires to make it work.

    V1 fuel pumps are historically weak and with the age I would get a new in tank DW300 (or Walboro 255) and do away with the BAP. Much more reliable and the OE pump can get to the point where it doesn't flow at all above a certain pressure no matter how much voltage you throw at the thing.

    As stated, LS2 TB won't get you anything. I really recommend to ditch it for either an IW or Summit (cheaper) overdriven crank balancer and make sure to pin it during reassembly. A set of 1 7/8" headers will add power throughout the RPM range while adding a distinctive growl.

    In all reality, you don't need anything more than a stock replacement oil pump. You can spend more but it won't get you anything. If you're at the point where you actually need an aftermarket HV/HP pump you likely have deeper issue's like a spun cam bearing or something.

    Most importantly, go to a well known tuner. A Maggie tune using the OE OS is not hard at all, but the MAF and VE table need to be adjusted using a wideband. Do not settle for someone raping the PE (power enrichment) value's and calling it a day. Try to see the before and after tune to see what was changed...this can be done quickly and easily.

    My $0.02. Take it or leave it.

    I guess.. I did not ask the extent to which he modified my tune however I don't know why he would fabricate numbers and give them to me? Either way in my case it was the logical path, may not be that way for everyone but it worked out for me and if/when the ls6 tb craps out I would definitely recommend it.

    My bad man, it's Jegg's that has one for about $300. Their catalogs are a little ambiguous stating an "Overdriven balancer for use with superchargers" although it says it's the standard 7.5". One has to be a typo...I'll call tomorrow and see if I can get some more info.

    I believe you are looking at this part:
    http://www.jegs.com/i/JEGS+Performan...16253/10002/-1

    Last time I talked to Jegs they said ti does fit the CTS-V also.

    Perfect. Now to make sure it is actually 10%OD not 7.5inches thanks guys. Anyone have problems running OD on the other accessories?

    ----------

    This is why innovators west offer all the other pulleys. They are 10% undersized to accommodate the 10% overdrive balancer.
