Stage 2- 525HP


Our custom tuned flash adds 100hp/100tq when paired with one of our hand crafted 2 muffler sport X design exhausts with 200 cell cats. The stock exhaust is very restrictive and at higher boost levels it increases the EGT’s dramatically meanwhile decreasing power as well as turbo spool time. We hand craft the X design exhaust to client needs. Please call for more details. Price may very depending on the exhaust options selected. One of our clients trapped 123.84 mph in 1.4 mile on our 93 octane tune and exhaust only. for more information and your custom tune call Markski direct at 773-980-6550.
