I know this has been discussed, searched numerous threads and can't find a definitive answer. Running a 6265dbb, have it at 22psi. Just installed a FAST classic to control. Looking for the best way to ramp boost with an internal wastegate (RJC pipe with big puck and RJC controller). I've ported...

Just wanted to express my sincere gratitiude to the Hartline's. I had phoned last minute in regards to a start up program for my FAST. Somewhere in their busy schedule Cal was able to fit me in, obviously working well outside business hours. Many many thanks, Kudos to the Hartlines! Mark...

Installing a FAST Classic, does it require an IAT relocation? And if so, will the up pipe be adequate, or should I tap it into rear of dog house? I run Alky on car. Many thanks in advance. Mark

Just confirming, the FAST Sequential system will control the on/off of the second pump with the Racetronix Double pumper? I was advised the Aux.#2 will, based on MAP and TPS inputs. Any issues using this over the optional Hobbs switch? Thanks, Mark Posted from the TurboBuick.Com mobile app

Looking for advise on RJC pipe fit and puck alignment....the pipe hits inner fender well and frame when installed, no room for adjustment at housing. Next issue seems to null and void "clocking" the pipe/turbo because the oversize puck barely covers my turbo wastgate hole (PT 6265dbb, unported...

I am currently running Autolite 24 plugs in my GN1 aluminum heads and heard they might not be the recommended plug. I haven't noticed an issue but want to run optimal/proper plug. I'm currently running 22 psi with moderate alky and no knock. Thanks

Here's a recent powerlogger file. Boost is closer to 20.5psi on gauge as map signal voltage was 5.34v, not 5.0v (will be using TPS 5v signal). any insight is appreciated, I'm new to tuning.

I just switched to the 3.5 LS1 Maf and translator, am using the Commander chip. What do I need to do if anything?

Curiousty is killing me after reading other threads...whats the potential for around 25psi..... Here's the combo: 109, GN1 aluminum w/roller rockers, ported doghouse and intake, 210/214 roller cam, diamond forged pistons, LS1 maf, 6265 dbb w 3" downpipe and 2 1/2" exhaust, alky, 94 octane...
