m370 intake manifold. its too bad they dont have a before and after on the manifold. you pick up 8-10hp and 10+ torque from 2.2k to 7k but you lose a few after 7k.

well you can blame me for no before dyno numbers. I really didn't care what the gains were per say I just knew what I wanted installed and if the Tune didn't require the dyno I wouldn't have even cared to see the numbers to be honest. All I know is, it sounds like a sports car now, even with just the exhaust it sounded great but combined with the other mods even better. right now I think I'm overpowering my stock wheels until I get the new tread on there it's difficult to launch in 1st and maintain grip into 2nd so I haven't really been able to tell from say a flat 0-60mph, but I can tell you out the highway it no longer feels anemic which when stock at around starting at about 75-80 and gunning it does didn't feel like it had enough. Now, it obviously isn't a charger or camaro SS on the top end but it sure does alot more powerful in the highway speeds.

it's fast a hell anyway stock from 0-60 but i imagine it's better now if I can get traction but I'm most happy with it's overall sound and just more powerful feel throughout the powerband and espcecially up top where it felt like it needed. anyway thats my 2 cents.

here's an example of my problem going 1st gear starts spinning around 5500ish I think and into 2nd, when I glanced down I could see the VDC flashing pretty crazily. Yes I had it on... and oh yeah I was finally able to download the Torque sync agent so I could encode my video with any of the stats
