Brenspeed “Corvette Killer” Stage 3 upgrade
 
I have an ‘07 s281sc and considering buying the upgrade kit to go from 465 hp to 530 hp. Anyone offer any insight?

That’s the kit I have. Makes a big difference

Well worth it! Got it for my '08 a few years back. Only thing I would suggest is to get a better tune. The tune they sent me was useless, get someone in the car to tune it and not a canned tune. If I had to do it over I would get a 3.2 pulley VMP $129.00 (smaller than the kit for another pound or two of boost), 39lb injectors (same as kit), JLT cold air intake $259.00 (same as kit), VMP boost a pump $329.00 (plug and play) in place of the KB (need to cut and splice wire), vacuum line you can get at Advance to make your own (and cheaper), Autolite HT0 plugs (auto parts store or rockauto about $10 bucks ea.) and last find a good tuner and just get the SCT from them when they tune the car. That's my .02

Call JDM Engineering. (www.teamjdm.com) They can sell you the same stuff and can do a custom tune. Their tune won't be "off the shelf" and your car will run Iike it was new.

I’ve been running this setup on my 2007 Shelby GT with a Saleen series 6.5 SC Long tube headers, 3.73 gears. I ran it with the boost a pump for several years and then in 2011 I upgraded to a GT500 fuel pump. The car has over 58k on it and 50k are with the Supercharger setup as described. I’ve run the car at the drag strip and road course with out issues. I’m running a a 3.0 pulley making 498RWP on a 91 Brenspeed tune 518 on race fuel ( I live a 5,280 feet so I need the smaller pulley to compensate for the altitude). I also have JDM tunes for the car. It’s a great package.

Help!
 
I have an 06s281sc. I installed the stage 3 and now I'm having issues with the engine fluttering after cold start. It clears up in a min or 2. Engine light came on throwing a bank 2 running too rich code. I have the brenspeed tune. I didn't get the catch cans but I got everything else that was recommended. Anyone else familiar with this issue? I NEED HELP! PLEASE!

I just sold my car sadly, she has 155k miles on it with the Brenspeed stage 3. In the mornings she would act the same and then clear right up. The only improvement I found with this issue was spark plugs but inevitably it persisted. Not really a big deal but annoying

Mine didn’t run great when cold but was fine once warmed up. I never threw any codes. Have you contacted Brenspeed? They should be able to tweak it.

I've had the Brenspeed 530 hp tune on my 06 GT for about 4 years and it runs just fine - real strong. I drive it just about every day if it's not raining or snowing. Haven't had much of either for quite a while so I'm enjoying the car while I can.
