I recently installed my II silver 62 turbo and getting a turbo underboost code every so often (P0299). I'm assuming due to the laggy nature of the turbo (with my 37" tires and 3.73 gears especially)... its setting it off; and gets cleared w/ my smarty jr. Funny enough, if i stand on the throttle, ill set an overboost code (in which im getting a quadzilla boost fooler for that).

However, I have searched and found no exact answer to this problem for the underboost code. From what I gather an Edge EZ may solve this issue? Is this the only module/box that would prevent this underboost CEL to occur?

thanks.

 

Anyone?

 

yea i have the same problem and still havent figured it out, it tends to come a few times in a week then it wont come on for a couple weeks then it will come on a few times a week again
