Im in love!!! Got the performance back out of my car. The K&N intake and HFC created problems without a tune. No major problems, but my car was running super rich and I could feel a difference. . He reset my shift points and the throttle response is now spot on. World of difference. He also said that if I had the STILLEN intake that I might get an extra 8-10 hp at the wheels. This is due to the amount of extra heat the K&N set up is taking in. The stillen is apparently more efficient. So I went from 184/229 to 214/246. I am happy with the gains I got, especially considering how hot it was during the dyno. The guys and girls at MAC autosports were great. Will return and send any business in Denver their way. The first pic is of the baseline. (Keep in mind that I live at amost 6000 ft. Hence the lower #'s compared to other HR's.)

 

Some other cars in their Garage!!! The 240 was throwing down over 420 on the dyno.

 

^ woo, those r nice

 

Thats would be about ~280+whp at sea level which is good bit of power! the band seems really nice, post some driving impressions after you drive it for a few days.

 

sweet i can't wait for my tune

 

Nice, congrats!

 

Yeah I figure a bone stock HR should pull around 260 if you factor 17 percent loss through the drive line. Then lose another 15% of that for the elevation up here, 3% per 1000 feet. That would put you at 221 whp. That doesn't seem right for some reason. lol. I will post some driving impressions soon. Just got back from a cruise and the new shift points are real nice. I now have the power available more frequently. Once getting up into slightly higher RPMS the shifting becomes kinda harsh, but it is so much quicker (the shifting). He said this is for the sake of the transmission, before it was somewhat slipping. If it is too much for me he can ease it up a little bit. I like it though. Most notable is the shift points and the new torque curve so far.

 

Nice man, keep us updated. Really wanting to get tuned now, but gonna wait till I change my cats.

 

Awesome Results! I've got mods coming and will be living out in CO very very soon! Might have to check out MAC when i get ready for my Tune!

 

Glad to hear good impressions, especially ab the shifts. My G is getting dyno tuned with osiris this saturday so I'll have to give my impressions as well...can't wait. Glad you received good results

 

Yeah hopefully you are as happy with yours as I am with mine. Let us know, and post some results if possible. Now that I have been driving a bit, I need to have some minor adjustments made. Shifting from second to third sometimes takes me up an extra 1000 rpms than I would like. It sometimes goes up to 5k when I am only at 1/2 throttle. A bit much. lol but not bad at all. I could live with it easy but...... I might as well get it perfect.

 

I plan to share my results this weekend for sure. Very interested in the new feel after the tune. So I'm guessing you also have some new maps that you've tested out as well? Economy/anti-theft/etc.?

 

I'm glad you went. Lets race sunday when I'm back from StrikeForce !! Love MAC!! Solid people

 

For MAC to do multiple maps will be extra $$$ im sure. We spent 2 1/2 full hours tuning. The auto has more adjustments to made as well I am told. Their rate is 190/hr. I paid 750 flat rate for my custom map and the license, which was cheaper than expected since it is an auto. I would like to have a few extra maps made that would be accessable through the Cruise Control. In the future....

 

Nice looking numbers
