I installed some GSC 272/272 cams this past weekend...I can't believe how much low-end torque I lost. I had read about the 272's being a couple lbs short on torque on the low end, but didn't realize it would be this bad. Compared to the stock cams, my car feels like a 4cyl. Honda below 4k. Top end has improved but at quite the expense of low RPM power.

Is this something I can hope to have remedied by a re-tune? Right now I'm running a mail-in flash for 3" TBE, Helix Intake, Walbro Fuel Pump and boost controller set at 21psi.

It would be nice to get that torque back but I'm guessing since the retuning seems to only affect WOT/in boost driving I probably am out of luck...

 

I'd like to know too.

 

i too was not to happy with my 272's , but i didnt feel like i lost any tq , just didnt feel like +20-30hp . Allmost sound like the timming it not right , recheck to see if your timming marks line up

 

Yea after flash should be fine i have greddy 272's and tune was good 348wqrt..

 

I didnt know greddy makes 272

 

yea the timing is dead on...

the car pulls really hard up top but I definitely expected a bit more from all the "just installed my cams!!!" posts

 

Yea miss it lol

 

You definitely need a retune.

 

Did you go by the crank timing mark or the valve cover marks?

My crank was at btdc while the valve cover marks were dead on. I went with valve cover markings.

 

get it tuned...

 

The exhaust cam looked to be a bit past TDC but with the valve cover on it was perfect.

 

Retune that boy. Try Ecutek.

 

what about the crank pully timming mark ?

 

crank sprocket was also good. It definitely isn't timing. The car idles smooth as can be with a slight lope, never stumbles at all, and no CEL. If I was one tooth off I think the SES would've came on.

I have a retune scheduled for the 23rd at Turbotrix.

 

you should be fine after the retune, even with just 272's there should be minimal loss at low end
