So overall would you say the m37p was worth the purchase. I have fast intentions resonated testpipes on order and I was holding out on tuning because of the manifold. Really want to jump the gun on some long tube headers but not sure if that is a smart choice.

I love my M370, mid range and low end FTW. I'm making all my TQ before 3500 RPM's

since you already have test pipes and probably like or don't mind the loudness, long tube headers might work for you. They are one of the best performance mods. I didn't go with LTH because of the loudness, possible rasp, and the possibility of the check engine light showing up.

As with the M370, well I'm not really sure since the dyno was taken on a very humid day. I'm yet to take the car to the dyno after the tune to check the real improvement.

Alright thanks for the quick reply man ! Saw your mustang dyno # and they were good but hopefully.you could get a dynojet one down soon ! Should have made a thread like yours when moding my car. Only thing is that dynos are dirt cheap for you ! New to my g37 owned the car for about 3 month now.

I just read through this entire thread front to back. Hope I'm not subscribing too late and you have some more mods on your list. Thanks for this!

Glad to share my experiences.

You're still on time lol. Hopefully, many more mods to come.

It's a great thread right!? I caught it early in my myG37 days and was able to make some decisions based on Mr Alfredo24pr's dynos n reviews. As for being too late I'm certain we are all still in for several more informative, dyno backed results from this guys build thread. Once again big thumbs up A!

Alfredo, did you ever re dynoed with the m370 manifold ?

Not yet. Last one was with the M370. I am missing one dyno run now after the tune.

I too have been following this build thread as I am contemplating what route to take with mine. However, I noticed you went to Capitol Raceway. That track is hideous for getting good times. Absolutely terrible. MIR will give you the best times, hands town. I am going next Sunday (found out there is a test and tune that day) and if you want to meet me there, that would be awesome! Looking to get a 13.7 considering the cool weather. Im 100% stock.

It's actually Salinas Speedway in Puerto Rico (it is mentioned on the top right of the time slip). I don't know why the time slips appear as Capitol Raceway in Maryland. Maybe they are both hideous to get good times? I would go to MIR but Im stuck on an island lol!

Neddy_G37

bummer. Not that you cant go to the track with me but that your stuck on an island.

Will post my results when I get back next weekend!

Why no 19s? No plans on lowering?

I was looking for a slight drop with coilovers, but the price of those plus the camber kit is a bit high and I'm ok with the stock height. (for now)

We will see how the car will look with the aftermarket 18's to see if I can keep it stock height.

More importantly, I wanted to keep the 18" for the lower weight per wheel. The 18x8.5 are ~16.5 lbs and the 18x9.5 are ~17.6 lbs.
