hello yall i have a 2010 srt8 i just got and so far ive added a typhoon k&N intake and removed the resonatores and isntalled 2 super 10 flowmasters- im extremely please with results so far and as it stands it sounds great- my question is does this car need a retune now to optomize performance? what tuner is the best value to buy? im extremely computer and gadget savvy but have never messed with anything dealing with automobiles- im 27 and have had 2 cars prior but none this beastly- i really want to optimize the cars potential as it is now and also will be either switching to high flow cats or more likely just removing the cats all together( i removed them on my 95 mustnag gt 5.0 and my 2004 gmc sierra 5.4 or 5.7 idont remember) im also planning to swap headers in a few months but thats not high on my list and probably will be the extent of mods i do as i dont want to butcher it or change too much- any advice would be greatly appreciated i dont mind dropping money on a nice tuner but i am really trying to understand which is best value etc.. also i dont want to void my warranty so im trying to get some advice from some srt8 experts- thx!!
