National Speed Tuned 331/318
National Speed Tuned 331/318
Got tuned at National Speed in Wilmington, NC and ran 331/318. Currently running on 93 octane and setup consist of Injen SRI and ETS DP, HFC, V2 Extreme Exhaust, Tubular Manifold, and 4" IC w/ piping.
Yeah, I was expecting to get more into the 350-375 range, but they were having some issues with their wideband sensor so we didn't push it too hard. I'm going to be going back pretty soon, but before I do I'm going to throw on a EBC so we'll see how it goes.
They do a little bit of everything, but they have worked on multiple Evo platforms. Plus, I didn't find any other shops in the area that I trusted and had the same reputation. I was completely satisfied with their shop, customer service, and experience level.
National speed caters to Evo's? I thought they were more a DSM/all around shop?
Yea the numbers do seem alittle low. One my friends had his evo x tuned there but they kept messing up his check engine light kept turning on and it was throwing a lot of different codes. He ended up taking it somewhere else and ended up with around 390 whp with intake full exhaust boost controller new fuel pump injectors and ic pipe.

IMO Numbers are not that bad. I think the fact that he is only 24psi is also holding him back.. all the higher numbers usually have 1-2 more psi of boost. Graph looks smooth.. I wouldnt worry about it OP and enjoy the car.

That is true my peak boost was at 27psi. The only thing that would worry is that AFR spike right before redline. Looks right at 13:1
Yeah we didn't alter the boost at all and it was done with the open ecu. I haven't had any issues since the tune (ie CELs) and I drove it 850mi to Indiana not long after. It looks like the a/f spikes when they left off the throttle.
