went LEAN

[SikRacing97GST]

Alright guys this sucks. I recently installed the fp t28, ported 2x exhaust manifold, 02 dump. Ran great for about a month. Turned up the boost to 16psi. Now im extremely LEANed out. Im cheap so im going by the sparkplug readings. I just ordered the walbro 255lph, should be here wednesday, but is this going to solve my misfire and such and the get alot more fuel flowing. I have a b&m (only increases) afpr sitting here but it hasnt been installed because ive heard nothing but bad things about it. Whats causing me to run so lean? By the way: My autometer fancy A/f guage is saying full rich ... Lemme know what u think the 255lph will do for me. Oh and the stock fuel pump currenntly is rewired..... Tony

Here is you mod list.

"undisclosed"

How would you like us to hel you if that is all we have to go by? Perhaps that shold be our answer.

The problem is that you dont have injectors or a way to tune. You are maxing out the stock injectors and running lean, a fuel pump will help but it wont be a fix.

And there lies your problem. Tunning it this way on a turbo car will not work. You'll need some way of knowing whats going on. Save your money and do it the right way before you melt your motor.
