Ok I have on 03 Cav with the GM supercharger kit and the GM reflash. I have read that the reflash runs rich and you can do a few mods and everything will still run fine. I was wondering if anyone knows what kind of stuff I can do to make the car faster and the reflash will still work fine. Can I go to a smaller pulley size and if so how small? Anything else anyone would recomend for a little extra acceleration?
Others have pullied down with the reflash, but I wouldn't suggest that after seeing what idc's looks like with the stock pulley.
Look into Exhaust and possibly mild cams.
I maxxed out the 370s on the dyno with the stock pulley....
So regardless of whether you're running hpt or the reflash, you wouldn't pulley down without getting larger injectors so you don't lean out and go boom... which you can't tune for if you're locked out of the reflash... right?

I have been running the 3.0 pulley for over a year and a half with no problems

Same here...seeing 11:5 - 12:0 a/f at WOT...not a problem one!
Eh...old man with a Corvette now...it was bound to happen sooner rather than later right?
i cant say i havent had any problems, but i havent had anything major. just the occasional surging at idle..
anyway, running the 3.0 pulley with no major problems, getting my wideband back from innovate thursday so hopefully this one works and it will be all hooked up ready to go on friday

You guy's that are running the 3" supercharger pulley with the GM reflash... Did it make a differents in power and what other mods have you made besides header, exhaust and intercooler?
I never had my boost guage hooked up on the stock pulley set-up, however with a 3.0 pulley I am pushing 15psi on cool nights, and 12-13psi all the time, even when it is hot outside.
I have a 4-2-1 header, full 2.5" exhaust with a hi-flow cat and no resonator along wiht a 3" intake/K&N filter and a pretty larger intercooler. Also to help things out I have my B&M Shift plus for the Auto tranny. I keep it on 1 unless I want to play a little bit and then I put it on 2.

15psi... On the GM Reflash? What are you using to monitor your A/F ratio for leaning out to much?
when i was supercharged i had a 2.9 and was still running rich, pulled like a mother too
i just got tired of the car and retired it
swapped, supercharged, intercooled, 2.9, fun

Dayum... So from what I'm hearing... the GM reflash is not as Down Tune as everyone is saying?!?! Is there a real need to go with HP Tuner?

Well I just got my 3.0 pulley ZZ Performance and a CX Racing heat exchanger... Ill install them next week and see how it runs... Thanks every one for all the help!
i have a heat exchanger faq in this forum (boost forum). isnt a sticky so just look for Compiled Heat Exchanger Information

I don't see 15psi....cool night I can hit 14 but average about 12-13.
I still run pig rich even on cool nights...WOT too...the GM reflash (at least mine) is way, way rich all the time!

At WOT on a cool night...max of about 12:0...typically I see mid to low 11s on a normal Texas night.

Yeah... I read it before... lot of good info there... I'm running two 9" fans on the front of the Heat Exchanger... Thinking about running Moroso Cool Can that you can add ice to, on the outlet of the Heat exchanger... Might be over kill... I'll see how the small fans work first.
