    Re: Chips

    Swap in an L37 engine, trans and PCM. That'll give you the extra 25 HP, but remember, you won't realize that extra HP until you are at 6500 RPM. How often do you run there? That's a LOT of work and expense for a measly 25 Hp.

    Bottom line: It ain't gonna happen (in the FWD configuration). ......... and, as Ranger posted, the 3.11 economy/cruise final drive is also a BIG factor.

    Every day 20-30% of the time. I would also like to have some more oomph for track days.

    That's 250# less than our Sevilles - not enough difference to matter.

    Re: Chips

    LD8 is easily tuned and not that expensive to have it done. I have an LD8 paired with a Cadillac 3:71 trans I am going to install in my '97 Aurora, along with a tuned pcm from Madtuner. I also have a 'GXP Bonneville strut tower brace I am going to install on my car in the next couple days, just got done test fitting it.






    Here is a quote from the Madtuner website about tuning a Bonneville GXP. I can assure you Madtuner is legitimate, and easy to deal with.

    "Madtuner dyno-tunes first Bonneville GXP
    Monday, 23 April 2012
    We are pleased to announce that we have finished developing the software for and dyno-tuning an entirely stock 2005 Pontiac Bonneville GXP with good results to report - the car gained 10 FWHP. We did not move the forced torque converter lockup on these runs, so there is a bit of a dip in the graph where the peak gain would have been.

    We would like to extend a special thanks to Sarah C. for lending us her vehicle, Juan T. for doing preliminary testing of our tuning, and Tony and Dan of Finish Line Performance for excellent dyno support. Stay tuned for additional Northstar development and full/custom tuning support for additional vehicles coming shortly after our vacation."
