Lund Racing is a solid choice, really helped when I blindly lept into the gt350 manifold swap, and his customer service is top notch...nothing but positive things to say throughout the entire experience.

Thanks everyone, I'm still gonna shoot for 460 wheel on the stock cams (gonna try some further VCT manipulation) before I call the stock cams maxed... For reference my car with nothing more than a tune and CAI put down 392 on this same dyno..on one of my higher rpm pulls stock vs now I'm up...

Gibbo205 are you running a 93 or the flex fuel tune?

Thanks man, that was prior to my most recent dyno, I have since gone to the roush MAF tube (105mm).....455 hp will hold me until I can allocate funds for a set of cams

Also, I just noticed that the scalar for HP and TQ are setup differently ( the vehicle ahead of me was a 01 lightning, lotta tq not so much on HP) so I didn't rescale them and that is the explanation for the lack of crossing at 5250 rpm.

Disclaimer, all of my posted dyno sheets have been in STD, to me this creates a level playing field for all runs my most recent run was actually corrected down....as promised This was my last tune from lund (flex tune) (444.26 hp), Mods: GT350 IM GT350 TB Steeda CAI Pypes catted Longtubes...

So, to update this thread...ive since picked up hp tuners and decided to try my hand at tuning my own car (previous experience with hondas) and learned quite a bit and developed a pretty good pure 93 oct tune... dyno results will be posted shortly

Terminator2, pm me if interested ive got hp tuners and a street and dyno proven tune for the 350im/tb/cai and longtubes....no surging or touchy throttle Btw i used to follow your posts quite a bit on the cobaltss forums

Terminator2 what is your take on a larger maf cai vs a stock sized housing/velocity stack and high flow filter.....im currently running the latter, just wondering if you think itd be worthwhile to up maf housing size on the gt350 setup and headers or just a wasted investment

Thats a proper way to get a better clutch..lol

I do, but i had an issue post install Longstory short use a vacuum style bleeder on the top of the mastercylinder and only use dot 4 fluid (sent a buddy o the store and he unknowingly added a dot3/4 fluid....basically i wasnt getting full extension of the throwout bearing and was getting locked...

I completed it on my back in a driveway in about 5 and a half hours, with an appropriate lift and tranny jack (and no beer breaks) that time would be sub 4 hours

Go rxt please, mcleod explicitly states the rst is not for competition use and in a n/a car you'll never have to worry about the rxt letting go

Its something with the advance trac, shop owner where i dyno confirms he pulls this pigtail before doing runs, keeps the car from entering limp mode on the dyno @bmrsuspension is correct

It has stock pedal pressure, but an actual feelable engage/release point

Agreed

I do, i have the steeda spring.....never had any high rpm lockouts or any other clutch issue before...thats why it caught me off guard

Yeah mine exploded at the top of 3rd gear

I have had the gt350 intake manifold setup for a while now (installed back in January)....listen to your car when it starts talking to you, i.e: A couple months back my car developed a slight vibration that could be felt in the shifter (I attributed it to the fact that the MGW mounts to the...
