some new numbers after installing our 3" downpipe, a little more boost and a tune on hp tuners. 360 ftlbs and 275whp ![http://www.synapseturbo.com/gallery/cache/1ecee7327305b2cdff33ad87538a53ccc8ae9e0b_800.jpg](http://www.synapseturbo.com/gallery/cache/1ecee7327305b2cdff33ad87538a53ccc8ae9e0b_800.jpg) ---

Do you think the 3" downpipe is a little too much for the OEM turbo? I only ask because it looks like if boost onset has been shifted to the right a bit. I wonder if a 2.25 or 2.5 would better serve the car? Either way that’s a lot of power from a downpipe and a reflash. How much boost before/after? ---

The factory downpipe is 3" too, but is full of convertors… The midpipe is 3 inch also but reduces down to 2.5 inch farther back. Morgan or Mike can confirm but I think boost spikes to 21 and holds @ 19. Obviously not in its efficiency range anymore so a different turbo is in the works. ---

I wonder if a 2.25 or 2.5 would better serve the car? Either way that’s a lot of power from a downpipe and a reflash. How much boost before/after? the graph is somewhat decieving. the reason it comes on later is because we werent loading the engine up as much on the tuned runs due to a certain issue with the ECU at sustained higher boost levels for which we have a fix on the way. like paul said the stock downpipe is actually 3". we just removed the cats. still has the stock 2.5" mandral bent exhaust on it. ---

Good info. Does the ECU have a factory set “cut” that effect certain load blocks? I know I had that problem on a few cars I’ve tuned where in very specific load ranges the fuel or boost cut set by the ecu would cause funky things to happen. ---

> [@crazybrew609](#): > > if you guys need any oem engine parts or sensors let me know i’ll hook ya up, if you need any other gm info i have full access to gm SI2000 I think my throttle position sensor is fubared… everytime I get into high RPM’s and go WOT (or damn close) the CEL comes on and the thing goes into limp mode :angry2 So gay… all happened right after I put my 3" pulley on (and before I got it tuned… I drove it around with just the pulley on slowly and it came on.) Now I have 42’s and a better version of the stage 2 tune and its still being a cunt. I heard you have to chance the p0068 to enable at 8000rpms but with the GM tune I think they already addressed that. Holy fucking thread jack. :nono Anyway, the SS/T is sick… glad to see somebody is putting the time and effort into domestics for once :giggedy ---
