I haven't seen anyone post over 500 from a Maggie, yet.
Here is the video to the dyno run.

lets just look at what you get for the extra money.

70 horse
rims brakes
and badge.

yes a manual. but not all are m6.

so for the money get the gt and put in a cam. and bolt ones. for less then the difference and get more horse.

the brakes are just cts-v(2004-2007) they are 350 for the set off of ebay.
cam is 450 or less for a big one from gm. hell stick the ls3 cam in and call it a day. or the liver dod delete for 1200
and intake and headers and exahust. so ok you got 3200 or so into it

We have a 6-speed GXP shop car and sort of wish we would have just got a GT. After all of the ones that have been through here and seeing what kind of power they make, the extra money could have been spent on big mods.

This is my fist post on here, Hello. Some know me from other boards.


I just wanted to say that when I first saw that video it reassured me that I made the right decision in the GT+TVS1900. Pulley swaps and re-tunes do the trick. (to a point the motor can take of coarse)

Does anyone have a picture of the shifter for the GXP? I suspect it is m ore like the CTS-V and GTO, not the F-body.

I will not buy a GT and swap in a manual transmission, I will not buy a GT and swap in a manual transmission, I will not buy a GT and swap in a manual transmission, I will not buy a GT and swap in a manual transmission, I will not buy a GT and swap in a manual transmission........

Yea the 440hp ones I've seen are with stock pulley and stock exhaust. If I were going FI, I think I'd go with a ProCharged setup like WreckWriter has, his is basically right at 500rwhp, and has room to improve.

That was when he was at 10lbs boost, he has since turned it down because of fuel pressure problems. Stock on the TVS1900 is 6lbs.
