So im sitting here while my car is getting tuned so I decided to update. So far it has hit 250hp at 3800 rpms

 

whose tunning it? and what all is done to it. im in nc also and may be in need of a tuner

 

Mayhem motorsports in raleigh, ita got a 2.8 on a tvs and 80 pound injectors w a return fuel setup, they r having alittle trouble with the fuel cause its cutting off around 4000 rpms

 

You better hit 300. I know people that hit 250 on a 2.8 m62..
Good luck keep us updated

 

Im at 250 halfway through my rpms, im sure I will, but ty

 

m62 and 2.8 300whp?

 

Learn to read... Think about it

Yeah you jonathan

 

DUDE! I'm gonna have to check them out. I PMd the dude you told me tunes Cobalts in Raleigh but he never responded is that the same guy?
And I still wanna get those LSJ parts from you man hit me up I wanna see the car after the tune! Good luck

 

i hit 250 on GMS2

 

People, please carefully re-read the OP's first post.

He is making 250whp at 3800rpm. Once he gets the fueling issue sorted out he should def see 300+whp.

 

At 6400 rpms im at 314/299, so im pass 300, 800 more rpms to go, video will be posted qhen I get home

 

No these guys r better, im at mayhem motorsports, u should swing by

 

I highly doubt that shop is better if they are having issues with "fueling" at 4k rpms, roffle. Hptuners by recommended members > shops who don't know our platform.

Also without high octane on the TVS you won't ever see it's true potential. Either use e85 or meth.

 

oops lmao my bad guys i totally missed the part that said tvs on 2.8 lol.

 

Its on e85

 

Torque is looking good. Should be able to get quite a bit more power out of it though. Do you know how much timing they are running?

 

25 degrees, and 316 was the final number. I need a 3 inch exh and down pipe, he showed me how it was restricting power

 

What exhaust are you running right now? Header/dp/catback? Also what was the AFR?

 

pacesetter header, some fabed up down pipe and 2.5 megan exhaust. i think im gonna go with the long tube header and 3 inch exhaust from ottp. i cant remember my afr but ill check next time i get in the car. also he told me i need remove the maf and go with some kinda system which i forgot what he said its called

 

I wouldnt remove the MAF. Our ECUs dont have a whole lot of control when it comes to speed density tuning. Also, on our cars the MAF can read to ~16,000hz so if he was saying get rid of it just because you may be going over the 11,000hz control limit there are ways around that other than deleting the MAF.

 

oh dear...

 

what he was talking about was basically deleting the whole intake its self to have less restriction. i told him i would look into it which i was going to. but i forgot what the product was called that he was telling me about

 

Damn man I totally would have if I had checked this earlier haha. And the only reason they were having problems with your fuel system is because you have the return style system right? Also, how did it turn out? Did they do a good job? And was it a dent to the wallet hahaha

 

it really wasnt i problem, i t seemed like it to me cause im not a tuner. but he was just doing it bit by bit because he couldnt find a map for my setup up to start off with. i think it turned out great and they are awesome people to work with. im going to go back to them to get my clutch put in. looking at my hp curve on the sheet he did show me how my pos exhaust system restricted horsepower. but it only costed me 500 and i hung out there all day jsut bullshiting with them

 

Wow sick price.
Now sell me the rest of your parts and help me install this supercharger so I can get it tuned as well
